Description

Carbon Dioxide transmitter E2618-CO2 is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include HVAC and air quality control in public, office and industrial buildings, greenhouses, underground parkings, boiler houses, and other confined spaces, where potentially toxic concentration of carbon dioxide can accumulate.

The instrument utilises a fully calibrated and temperature compensated photoacoustic or optical NDIR gas sensor with excellent repeatability, stability and long lifetime. Ambient pressure compensation (in the range 0,5...2 bar of absolute pressure) is available as an option.

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.
