The 200C 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 1 msec. The detection limit is 50 ppb (parts per billion) propylene in air and the full-scale measurement range is 625 ppm.
The miniPID has been used successfully for numerous olfaction studies involving humans, mice, rats, dogs, Drosophila, moths, mosquitos and ants to name just a few species. 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 and pump speed with a control for setting the zero. LEDs provide indication of power, and lamp status. A front-panel display provides fast response indication of the output signal from the sensor with an LED indicator for off-scale signals. Simply plug it in, turn it on and quantify odors with sub-millisecond response time.
