Honeywell MicroRAE — wireless 4-gas detector
The Honeywell MicroRAE is a portable, wireless diffusion detector that monitors up to four gases simultaneously: hydrogen sulfide (H₂S), carbon monoxide (CO), oxygen (O₂) and combustible gases (LEL). With Bluetooth LE connectivity and the Honeywell Connext network (Mesh/Wi-Fi), it transmits readings and alarm states to other solutions (Connext Plus/Pro/Loneworker, Safety Communicator), enabling fast, informed decisions. A compact, water- and dust-resistant housing and a no-motion alarm increase worker safety.
