CO-СO2 Transmitter
  • Simultaneous CO and CO2 monitoring
  • Range 0...300 / 1000 ppm CO and 0...10 000 ppm CO2
  • Resolution 1 ppm CO and 1 ppm CO2
  • Two SPST relays option
  • 2 × 4-20 mA or 0-10 V, RS485

CO-CO2 transmitter E2660-CO-CO2 is a member of PluraSens® family of multifunctional measurement instruments.

It is an excellent solution for underground parking garages. The device may be also used in other confined spaces, where potentially toxic concentration of carbon monoxide and carbon dioxide can accumulate.

For carbon monoxide detection, the instrument utilises an electrochemical gas sensor.  For carbon dioxide detection, the instrument utilises a photoacoustic gas sensor. Both sensors are fully calibrated and temperature compensated and 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.
