200B: Pheromone & Plume Tracking

The 200B miniPID photo-ionization detector combines small size, fast response, and high sensitivity in an easy-to-use, competitively priced package. It takes high frequency concentration measurements for pheromone/plume tracking both in wind tunnels and in the atmosphere. 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 in wind tunnel studies of moth and mosquito flight behavior at various universities including the Cardé lab at UC, Riverside. It has also been used outdoors to map plumes including a study of desert ants by Steck, Knaden and Hansson of the Max-Planck Institute. Proven reliable, and robust, our battery powered version (model 201A) achieved plume tracking while mounted on a wheeled robot by Bailey, Willis and Quinn of Case Western Reserve University.

The sensor head contains the detection cell, electrometer, RF-excited UV lamp and lamp control circuitry. The clean design 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.
