The 200B miniPID photo-ionization detector combines small size, fast response, and high sensitivity in an easy-to-use, competitively priced package. Designed for olfaction experiments, the sensor has a true frequency response of 330 Hz with a rise time of 0.6 msec. The detection limit is 100 ppb (parts per billion) propylene in air and the full-scale measurement range is 500 ppm.

The 220A Olfactometer provides reliable odor generation for demanding olfaction experiments. The 220A can be configured with 4, 8, 12 or 16 odor vials for maximum flexibility. Careful fluid design ensures repeatable odor profiles generated with minimum delay time between activation and arrival of the odor at the subject.

The 300C-I mechanical stimulator is an automated electronic von Frey device with the added capability to measure and control both force and length at a single application point. The 300C-I takes the variability and awkwardness out of applying force with a handheld von Frey filament or with other handheld mechanical stimulators.
