4-20 mA PID Transmitter

The RAEGuard PID is a permanently mounted (fixed) volatile organic compound (VOC) monitor using a Photoionization Detector (PID) transmitter that operates from a 9 to 36 VDC power source and provides an analog (4-20 mA) signal output in three full scale ranges* of 20 ppm, 100 ppm, or 1,000 ppm isobutylene equivalent. Housed in an explosion-proof enclosure, the RAEGuard PID is equipped with a local digital display of the gas concentration and functional keys for performing calibration.

* Ranges are not selectable, and must be specified at the time of order.
