Olfactomètre TO9 evolution

L’information demandée n’est malheureusement disponible qu’en anglais. Cependant, chez Olfasense nous avons des employés qui parlent français. Veuillez nous informer si vous préférez continuer la conversation en français.

The TO9 evolution olfactometer has all the functionality of the TO8 evolution olfactometer, plus the dual-forced choice method.

The maximum dilution increases to 2¹⁷ allowing you to measure samples of higher odour concentrations than is possible with the TO8 evolution olfactometer.

Just as the TO8 evolution, this olfactometer can be used equally as a home-based laboratory, as well as a mobile on-site laboratory to keep sample storage time to a minimum, to increase flexibility, and to offer quicker reporting.

The provided WiNose evolution LIMS ensures the best quality at all odour measurement sites, by supporting you in fulfilling essential quality management and quality control procedures in your day-to-day lab operation and audit preparation.

The TO9 evolution olfactometer is available as 4-station or 6-station olfactometer and meets all requirements of EN 13725:2022.

Available as 4-station or 6-station olfactometer

Based on our experience we know that different odour laboratories have different requirements for their olfactometer. Thanks to its modular design, the TO9 evolution is scalable for up to 6 panellist stations. You can decide for yourself which is most suitable for your requirements; whether it’s a 4-station or 6-station olfactometer.

The TO9 evolution is an ergonomically designed olfactometer that focuses on the main sensor in olfactometry: the human nose. Our engineers have collaborated with professional industrial designers to focus on the interaction between man and machine. The height-adjustable nose masks allow the panellists to always sit in the optimal upright position, regardless of how tall they are. The centrally-located touch screen is easily accessible and suitable for both right- and left-handed users.

Installation Video

In our installation video, you will learn how easily you can unpack, set up, and put our TO8 / TO9 evolution olfactometers into operation – quickly and all by yourself.

Especially in the current corona pandemic, traveling is difficult and sometimes only possible involving a lot of effort. It is therefore important to us that you can put your new olfactometer into operation without an Olfasense employee on-site.

At the same time, our experts will support you with subsequent training on the olfactometer control software and the WiNose LIMS via TeamViewer and Skype, so you can enjoy a comparable feeling of on-site support.
