For environments where combustible gases can pose a threat to your workers and your facility, this personal wireless monitor provides the visibility you need for fast incident response. The ToxiRAE Pro LEL features the most extensive on-board gas library in its class, plus 55 built-in correction factors for improved accuracy. The wireless connectivity delivers real-time data about proximity to the lower explosive limit (LEL) directly to a central command station. And with a built-in man-down alarm, you can be confident your workers are safe. The compact design of the ToxiRAE Pro LEL ensures it won’t interfere with work activities, while the replaceable sensor, filter, and battery make it easy to maintain.

The ToxiRAE Pro LEL is the world’s first personal wireless combustible gas monitor. The ToxiRAE Pro LEL provides safety professionals with wireless remote access to real-time instrument readings and alarm status for better visibility and faster incident response . The ToxiRAE Pro LEL quickly detects and accurately monitors combustibles in concentrations from 0 to 100% of the lower explosive limit (LEL). With the most extensive onboard gas library in its class, the ToxiRAE Pro LEL can be programmed to automatically read in %LEL of the specified compound.
