MicroRae Wireless Gas Detector-GPS, Bluetooth, WiFi

The MicroRae 4 gas portable detector brings enhanced user friendliness and flexibility to wireless gas detection. This enables continuous, instant visibility of safety threats for faster, more informed decisions, to protect workers, facilities and the environment and to optimize operations.

The MicroRae is a wireless diffusion detector that simultaneously monitors up to four gases, including hydrogen sulfide, carbon monoxide, oxygen and combustibles (LEL) or HCN. With its different wireless connectivity options the MicroRae can deliver real time instrument readings and alarm status to other wireless offerings such as ConneXt Plus, ConneXt Pro, ConneXt Loneworker and Safety Communicator.
