Nitrogen Dioxide Detector
Nitrogen dioxide detector E2608-NO2 is a member of new PluraSens® family of multifunctional measurement instruments.
Applications include underground parkings, boiler houses, kitchens, and other confined spaces, where potentially toxic concentration of nitrogen dioxide can accumulate.
Two relays with closing contact may be used for remote signalling or ventilation control. The default alarm set-points are typically at 3 ppm and at 6 ppm.
The instrument utilises novel fully calibrated and temperature compensated electrochemical gas sensor 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 detector to safety or building automation systems.
