E2660-CO-LEL detector-transmitter is an easy-to-use instrument intended for simultaneous monitoring of carbon monoxide, hydrogen, methane, acetylene, propane and butane concentration.
The device may be used in underground parkings, boiler houses, battery charging rooms, energy storages and other confined spaces, where potentially toxic concentration of carbon monoxide and combustible gases can accumulate.
The instrument utilizes novel fully calibrated and temperature compensated 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.
