Nitric Oxide Detector-Transmitter

  • Stable long-life electrochemical cell
  • Detection range 0...250 ppm NO
  • Attached or emote sensor
  • 2 × 4-20 mA / 0-10 V, RS485
  • Two SPST relays


Nitric oxide detector-transmitter E2638R-NO is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include chemical industry, medicine, laboratories, and other areas, where potentially toxic concentration of nitric oxide 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 device to safety or building automation systems.

Two relays with closing contact may be used for remote signaling or ventilation control. The default alarm set-points are typically at 10 ppm and at 25 ppm. The flashing LEDs and an internal buzzer (option) give alarms as well at two set-points.
