RAE Systems Inc. offers the ToxiRAE 3 family of single-gas monitors and the Auto-RAE Lite bump test and calibration station. ToxiRAE 3 features a stainless-steel front cover to withstand harsh environments and is currently available in three models:hydrogen sulfide (H2S) and high- and low-range carbon monoxide (CO). These toxic gas monitors carry U.S., Canadian, and European safety certificates for use in hazardous environments in the oil, gas production, refining, steel and first responder markets. “The AutoRAE Lite bump test and calibration station work together with the ToxiRAE 3 to quickly and easily check for proper alarm levels and to calibrate as required,” said Thomas Negre, director of instrumentation products for RAE Systems. “The AutoRAE Lite will also be a favour-ite product for large corporate users who want to keep records of all calibration and alarm data.” All three ToxiRAE 3 monitors have end-user configurable operating-modes as either “operating days remaining” or “gas concentration” display mode. The detectors feature multi-phase alarms (vibration, 95dB siren and flashing light) for Short Term Exposure Limit (STEL), Time Weighted Average (TWA) exposure and high/low alarms. The ToxiRAE 3 is designed to be used continuously in environments with temperatures ranging from 20 to +60 degrees C ( 4 to +140 degrees F) and has an IP67 waterproof rating.
