Nitrogen Dioxide Detector-Transmitter E2638-NO2
- Stable long-life electrochemical cell
- Detection ranges 0...20 ppm NO2, 0...200 ppm NO2
- Attached or remote probe
- 2 × 4-20 mA / 0-10 V, RS485
- Two SPST relays
Nitrogen dioxide detector-transmitter E2638R-NO2 is a member of new PluraSens® family of multifunctional measurement instruments.
Applications include underground parkings, boiler houses, kitchens, and other areas, 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 transmitter to safety or building automation systems.
Two relays with closing contact may be used for remote signaling or ventilation control. The flashing LEDs and an internal buzzer give alarms as well at two set-points.
