The PGM-2500 QRAE 3 4-in-1 gas detector is a portable 4-in-1 gas detector with wireless data transmission function. The PGM-2500 gas detector is available in both suction and diffusion types. Continuous detection of oxygen (O2), flammable gas, and toxic gases including hydrogen sulfide (H2S), carbon monoxide (CO), sulfur dioxide (SO2), and hydrogen cyanide (HCN) provides safety assurance for workers in hazardous environments.
The QRAE3 gas detector's wireless data transmission function can transmit information such as instrument readings, alarm status, including fall alarms, and more to the ProRAE Guardian Safety System and EchoView Host Mini-Controller in real time to remotely monitor the field status.
