CO-NO transmitter E2660-CO-NO is a member of PluraSens® family of multifunctional measurement instruments.

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 nitric oxide can accumulate.

The instrument utilises fully calibrated and temperature compensated electrochemical gas sensors with excellent repeatability, stability and long lifetime.

Two relays with closing contact (optional) may be used for remote signalling or concentration control. Two alarm set-points are user settable.

Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the detector to safety or building automation systems.
