Nitrogen Dioxide Detector
- Stable long-life electrochemical cell
- Detection ranges 0…20 ppm NO2, 0…200 ppm NO2
- Two analog outputs settable to 4-20 mA or 0-10 V
- RS485 Modbus RTU digital interface
- Two SPST relays
- Remote probe option
Nitrogen dioxide detector-transmitter 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.
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. We recommend to set the output scale within 20-100% of the detection range.
Two relays with closing contact may be used for remote signalling or ventilation control. The default alarm set-points are typically 3 ppm and at 6 ppm for 0…20 ppm range. For 0…200 ppm range alarm set points are determined by user within 5-95% of the detection range.
