RAE Systems Inc., a sensor solutions provider, introduced MeshGuard -- a rugged single-sensor, battery-powered toxic gas detector integrated with a wireless mesh radio modem for detecting hazardous levels of hydrogen sulfide (H2S) or carbon monoxide (CO). The monitoring units are designed to operate in the full temperature range of -40° to 122° F or -40° to +50° C.MeshGuard allows for quick installation in hazardous locations, and remote readings for up to 24 monitors are displayed on the FMC 2000 wireless controller, according to the company. The MeshGuard monitors are intrinsically safe for use in hazardous atmospheres and weatherproof to an IP-65 rating. Each unit can operate up to six months without calibration or battery replacement. The radio range for the units is 300m (1000ft) line of sight, with each unit providing radio relay capability.
