200B miniPID Fast Response Olfaction Sensor

  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 miniPID has been used successfully for numerous olfaction studies involving mice, rats, Drosophila, moths, mosquitos and ants. Researchers and manufacturers have also been using the miniPID to characterize olfactometers.

The sensor head contains the detection cell, electrometer, RF-excited UV lamp and lamp control circuitry. The easy-to-use controller has switches for instrument power, pump speed and gain, and a control for setting the zero. LEDs provide indication of power, pump, and lamp status. A front-panel display provides fast-response indication of the output signal from the sensor.
