Description
Combustible gas detector E2618-LEL is a member of PluraSens® family of multifunctional measurement instruments. The device exhibits sensitivity to hydrogen, methane, acetylene, propane and butane
Applications include underground parkings, boiler houses, battery charging rooms, kitchens, and other confined spaces, where potentially explosive concentration of combustible gases can accumulate.
The instrument utilises fully calibrated metal-oxide semiconductor or pellistor gas sensors with excellent repeatability, stability and long lifetime.
Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the transmitter to safety or building automation systems.
