Description

E2660-CO-NO2 detector-transmitter is an easy-to-use instrument intended for simultaneous monitoring of carbon monoxide and nitrogen dioxide concentration. It is an excellent solution for underground parkings. The device may be also used in boiler houses and other confined spaces, where potentially toxic concentration of carbon monoxide and nitrogen dioxide can accumulate.

The instrument utilises novel fully calibrated and temperature compensated electrochemical 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.
