The ToxiRae Pro Wireless LEL Gas Detector from Rae Systems is the world’s first wireless personal combustible gas detector. It takes worker protection to the next level by providing safety professionals wireless access to real time instrument readings and alarm status (including man-down alarm) from any location for better visibility and faster response. The ToxiRae Pro LEL promptly detects and accurately monitors explosives and combustibles in concentrations from 0 to 100% of the lower explosive limit (LEL). With an onboard library of 55 correction factors, the ToxiRae Pro LEL can be programmed to automatically read % LEL of the specified compound. Now AutoRae 2 compatible. Please note: ToxiRae Pro models need to be loaded with the latest Firmware Version for compatibility to the AutoRae 2.
