TO9 olfactometer

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

The olfactometer meets all the requirements of a dilution device for olfactometric measurements according to EN 13725. Using the TO9 olfactometer gives you a complete description of an odour sample.

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