Our key activities
Product & material odour testing and optimisation
The way in which an odour is perceived can play a decisive role in the decision to buy, and hence in determining the commercial success of a product. In some cases, a product’s ability to enhance or reduce odours can provide a unique selling point. In others, the presence of unwanted odours can adversely impact the product’s attractiveness.
With the help of odour measurement and odour assessment services, as well as odour certification of products, materials and VOCs, we help you to optimise your products and ensure product quality.
Using sensory and molecular analyses, we find out how a product is perceived in terms of its odour. Selected panelists as well as customised measurement techniques and test designs ensure high-quality measurement results. Highly effective products receive the Olfasense ‘odour quality seal’.
Environmental odour analysis, assessment & control
Olfasense offers a full range of sensory and molecular odour analysis services to identify, measure and forecast environmental odours, assess odour impact, and help you define robust odour control solutions.
All of our services are offered in-house and we operate accredited odour sampling teams and olfactometry laboratories. Our highly experienced consultants are experts in odour control techniques and technologies and are highly skilled in the application of odour survey methods including odour dispersion modelling.
We typically work on behalf of industrial or agricultural facilities who are required to control odorous emissions as part of their planning or regulatory permits. We also work for regulators and provide advice to support municipalities and governments to develop odour policy. As pioneers in the digitalisation of odour measurements in the environmental sector, we also facilitate your procedures relating to odour management and complaints.
Equipment and technologies for odour, VOC and corrosive gas testing
Whether olfactometers, sampling equipment, VOC emission test chambers, corrosive gas test chambers, software and much more: Olfasense provides you with all the equipment and technology you need for reliable odour measurements, VOC emission and corrosive gas testing. For laboratories and environmental measurements. Individually or as a complete solution. Right up to the training of your team. Worldwide.
Over 400 laboratories, research institutes, universities and companies work with our solutions. Our olfactometer is the world’s most frequently used measuring instrument for odour measurement. You too can benefit from reliable measuring technology, robust measuring instruments and sophisticated software coupled with unique service and support!

Client feedback
Exceptionally user-friendly equipment with exceptional software and associated LIMS system. The after sales support has been second to none.
Mark McGarry, Managing Director at AXIS Environmental Services
Frans Vossen from Olfasense came to HMEL’s Guru Gobind Singh Refinery in Punjab, India to help us understand and deal with odor complaints from the surrounding villages. Frans left us with severable clear action items to reduce odors. As a result of his work, we have reduced odor complaints by over 50%. We searched the world to find Frans. He is the leader in the field of odor identification and elimination.
Martin Hawkins, COO, HMEL
We hereby would like to express our sincere gratitude to Olfasense GmbH for their contribution and overall provided assistance, continuous effort and technical guidance & expertise in the process of extending the scope of our EN 17025:2017 laboratory to odour concentration determination by Dynamic Olfactometry, according to EN 13725:2022 standard, with excellent results. We were lucky to get our hands on superior quality products, receive extensive training programs and compete in proficiency testing while feeling a part of a big family. The professionalism and supportive mentality of Olfasense GmbH made this quest an enjoyable and easy-going experience that will drive us through the future with confidence and passion for what is coming!
Apostolos Angelis, Head of Olfactometry Dpt. at ENVIROMETRICS S.A.
The TO evolution olfactometer and the services offered by Olfasense for the maintenance and calibration of this equipment enable us to offer our customers a high quality service (accuracy, repeatability and speed of analysis) to the highest international standards. We particularly appreciated the possibility of shipping Olfasense our dilution unit for the annual accredited calibration. By planning this operation, it did not affect the productivity of the laboratory. We have had the pleasure to obtain our accreditation according to ISO 17025 with our new equipment which has met all the expectations of the evaluators of the BELAC (design, calibration, data protection, stability, precision, reliability …).
Loïc Raymond, Technical Manager for odours and gas chemistry at Odometric
We have been using Olfasense’s emission test chambers since market launch and we are very satisfied with both the product and the service. In our recent ISO 17025 accreditation audit, the installed emission test chambers have been successfully approved by the German accreditation body DAkkS, and are now included under the accreditation scope of Hohenstein Textile Testing Institute.
Rainer Fusenig, Assistant Head of Laboratory, Hohenstein Textile Testing Institute
FORCE Technology has worked with olfactometry for 30 years, and for the last two years used a TO8 Olfactometer from Olfasense as our only olfactometer. We are very satisfied with the function of the TO8, which is easy to handle and have good report facilities.
Arne Oxböl, Project engineer at FORCE Technology
DSM Coating Resins makes products used in paints and lacquers, and is driven to low VOC emissions. For our VOC measurements, we have been using Olfasense’s EK250 emission test chamber for half a year now. We are very content with both the installation and the service of Olfasense. The EK250 is robust and easy in use and it meets our expectations as we are now fully compliant with the ISO 16000-9 standard.
Diane de Bruijne, R&D associate scientist, DSM Coating Resins
We would like to thank the Olfasense team for their help, advice and trainings from the beginning of foundation of our odour laboratory up to now. The whole process was simple and trouble-free, resulting in having an effectively functioning odour laboratory. Thanks for the excellent and fast service and I look forward to working with Olfasense for the foreseeable future.
Algirdas Keblas, National Public Health Surveillance Laboratory
Odournet UK Ltd [now Olfasense UK Ltd] have supported many of our remediation schemes over the past 5 years and we will undoubtedly continue to use them.
Dave Jacob, Principal Consultant, RSK
Odournet UK Ltd purchased two TO evolution olfactometers in 2015 and 2016, from Olfasense GmbH. Olfasense have provided a great service, with efficient supply and installation of our olfactometers and knowledgeable, friendly support whenever we’ve needed it. We were quickly able to integrate these olfactometers into our long-standing UKAS accreditation. We have always been very confident in this technology, but have recently received the results of the worldwide interlaboratory comparison that we participated in, earlier in 2016, and are exceptionally happy with our achievement using the TO evolution olfactometers. We were within the top 3 places, for accuracy, out of 36 participating similar odour labs!

Dax Airscience Ltd
We carefully selected Olfasense as a highly qualified and specialized consultant to support us in analyzing the odor/off-gases of a production plant in China. Apart from professionalism I consider easy access, flexibility and interactive communication on execution and reporting as the key elements that made this project successful.
Ron Thiecke, Director Safety, Health and Environment, DSM Sinochem
Our cooperation with Olfasense started a few years ago in the area of odours. (…) Excellent cooperation and trust arising from deep technical knowledge and skills also resulted in investment in a newly developed SK1500 noxious gases testing chamber tailored to our needs. The completely new product was delivered on time even though it was designed from scratch and we were kept informed on every step of the design and production of this unit. One single issue within a few months of usage was solved within 2-3 weeks by the designer himself. The expertise, knowledge and flexibility make Olfasense a really trustworthy partner not only a equipment provider.
Dr Krzysztof Brodzik, Materials Testing Department Manager at BOSMAL Automotive Research & Development Institute Ltd
For iLF Magdeburg GmbH, customer service comes first. We expect the same from our suppliers. In our view, Olfasense fulfills this in a first-class manner. The support and advice as well as the reliability of the Olfasense emission chambers are the decisive factors for us, which we will continue to rely on in future projects.
Dr. Ute Holzhausen, Head Materials Analysis at iLF Magdeburg GmbH
We have used Olfasense for service and calibration twice and appreciate the fast and reliabte service. Our olfactometer was out of service for only six days. lt was easy to arrange with Olfasense calibration department. We have a good contact with Olfasense’s technicians and get quick answers, when we have technical questions.
Arne Oxböl, Project engineer at FORCE Technology
My company has been working with Odournet [now Olfasense UK Ltd] now for several years to support our site emissions monitoring requirements. To date the services undertaken have been of consistently high quality. Odournet staff are professional and knowledgeable and take pride in their work.

Sayda Almendra Marmolejo Correa, CIATEC A.C.
Very professional staff, quick and precise answers, and quality equipment that meets our needs. An excellent partner for our company’s activities.
Giovanna Turturro, Lenviros srl
Odournet [now Olfasense UK Ltd] was able to respond quickly to perform an Odour Impact Assessment to support a planning application. The consultants approached the project in a professional and methodical way. The outcome of the study helped us eliminate fugitive emissions, improve our odour management practices and secure planning. I definitely recommend their services.
Henk Stoker, Solue Limited
Olfasense has provided technical support since 2000, including training, equipment calibration and technical advice. This has allowed us to apply olfactometry in the central region of Mexico to develop odour maps in cities with these problems, identifying the sources that cause them, the existing odour concentration and impact on the population, which has allowed to implement corrective measures.
Sayda Almendra Marmolejo Correa, CIATEC A.C.
Having worked together as consultants in a large odour management project in Doha, Qatar, we were able to develop a strong partnership, supported by Odournet’s [now Olfasense UK Ltd] experience and industry know-how and combining it with our engineering background, being able to bear all requirements under the scope and lead the project into a very successful outcome. We look forward to working with Nick Jones again.
Joaquim Beleza, Douro ECI
We have been using Odournet [now Olfasense UK Ltd] for several years to help manage our odour abatement systems on site. They have always been extremely pro-active, supportive and a pleasure to deal with.
Justin Dampney, Eco Sustainable Solutions Ltd
We have had an olfactometer device since 2012 and we haven’t experienced any technical problem until now. We have only had a little issue with the software of the instrument but Olfasense’s authorized staff was really helpful to solve it.
Sercan Soytaş, ARTEK
We were among the very first who introduced olfactometers to the local air quality assessment work in Russia by purchasing the piece of equipment at Olfasense. With Olfasense’s highly professional and friendly methodological and technical support we learned the technique and have been applying it ever since. We can attest that the whole cycle of our cooperation has been effective and pleasant.
SRI Atmosphere JSC
Our cooperation with Olfasense (operating under the name Ecoma at that time) began between 2005-2006 when we acquired our first olfactometer TO-8 in Estonia. Since then, we have continuously utilized Olfasense products and services, and what has intrigued us the most in our collaboration is the company’s precision, diligence, and willingness to assist in resolving various issues. Today, we continue our cooperation with Olfasense, and among other things, we acquired a new olfactometer TO-9 in 2020, with which we are very satisfied. The only thing that “old sniffers” occasionally miss is the TO-8 olfactometer’s flexible push buttons 🙂 Every new thing requires adaptation, and fortunately, a new generation is growing up at the Estonian Environmental Research Centre air lab, who are even more enthusiastic about operating in the field of odor assessment. At the moment, we can state that the field of odor assessment has been one of the most steadily growing services in our air lab. We hope to further enhance the quality of this service in collaboration with Olfasense and be prepared for possible innovations in the process of odor assessment!
Marek Maasikmets; Estonian Environmental Research Centre
Big thank you to all your team. Excellent support and excellent service from everyone.
Martin Futter, Element MTE
For many years we have analysed odour with an olfactometer from Olfasense. The equipment is very reliable, and we have never been in a position where it was not possible to perform the analyses planned. Only once we have experienced an error to the olfactometer. The error was discovered during in-house inspection of the olfactometer on the day before a large series of analyses – with quick and qualified help from the service department of Olfasense, the series of analyses could be performed as planned and within time limit established by the European Standard for odour determination by dynamic olfactometry. Excellent Service!
Ole Pontoppidan, Danish Meat Research Institute
Our experience with Olfasense has been very pleasant from the beginning. We have been fully trusting their advice and equipment to measure odours for 5 years. Their TO8 evolution olfactometer was perfectly adapted to our ISO 17025: 2017 management system, improving the quality of the results of our laboratory located in Chile.
Miguel Gatica, Deputy Manager Odour Engineering; Proterm S.A.
We have used Odournet [now Olfasense UK Ltd] for last 10 years and over this period we have found Odournet’s expertise to be professional, focussed and practical. I would definitely recommend Odournet’s expertise to be used by other businesses. They are good at what they do.
Naeem Hafeez, Veolia Water
I am delighted with the service provided, subject knowledge and professional attitude of all staff that I deal with.
Neil Chisnal, TEAMS North Ltd
AIMPLAS decided to purchase the Olfasense emissions chamber because of its professionalism, its proximity and, above all, the knowledge it demonstrated of the requirements of automotive standards. Something very important for us. During the installation of the equipment, Olfasense helped the AIMPLAS staff to understand everything that is necessary for the correct functioning of the chamber, demonstrating once again their professionalism. Without a doubt, it was a good choice.
Nuria García Batista, PhD.; Chemical Laboratory – Identification; AIMPLAS
Having worked with Odournet [now Olfasense UK Ltd] since 2012 on a number of high profile / challenging odour projects I have found their technical knowledge and support to be invaluable in ensuring that the appropriate solution is delivered. The flexibility of their approach and their regulatory knowledge has supported my team and I to achieve many successes over the years.
Peter O’Kane, Veolia
The course content was excellent. We covered all issues on the EN 13725 and a lot of the VDI 3880. However, the differentiating factor, undoubtedly, was Marc. Besides being completely flexible, and very, very patient, (despite being bombarded with questions!), the sharing of his practical experience both in the field and in the lab was what made the trip worthwhile. Marc’s commitment to customer satisfaction and follow-up were further confirmed by his making himself available for a session or two via Zoom if and when we have any queries in the coming months. After the training, we feel fully equipped to carry out odour monitoring to the EN 13725 Standard, while also incorporating the VDI 3880. Olfasense proved to be the optimal choice for their commitment to results, experience, and after-sales service and follow-up.
Ronan O’Mhaoinigh, University College Dublin
Odournet [now Olfasense UK Ltd] is a trusted supplier to Golder Associates (UK) Limited. They are approachable, reliable and meticulous in their work and deliver clear concise and accessible reports. The team will always do what they can to accommodate urgent/complex requests and are a pleasure to work with.
Ruth Fain, Golder Associates (UK) Limited
From SGS we want to congratulate Olfasense on the quality of its equipment and thank the technical support for the development of our odour test service.

With Olfasense we have been maintaining a strong and reliable long term supplier relationship for over 7 years. They have proven to be responsive to our needs by developing innovative and bespoke test designs in the field of deodorant testing.
Susanne Treibel, Team Leader Product Testing Deodorants, Beiersdorf AG
Our cooperation with Olfasense has started few years ago in area of odors. Since then, their equipment portfolio became wider and even more attractive for us. We are happy users of EK1000 materials emission testing chamber which strongly increased our capacity for emission testing with reducing the maintenance cost. Few issues have arisen since introduction however these were always solved asap. (…) The expertise, knowledge and flexibility make Olfasense really trustworthy partner not only equipment provider.
