Nitric Oxide Detector-Transmitter

  • Easy to install robust enclosure
  • Detection range 0...250 ppm NO
  • Two analog outputs settable to 4-20 mA or 0-10 V
  • RS485 Modbus RTU digital interface
  • Relay option
  • Remote probe option


Nitric oxide detector-transmitter E2648-NO is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include chemical industry, medicine, laboratories, and other confined spaces, 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.

To connect the detector to safety or building automation systems use two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol. We recommend to set the output scale within 20-100% of the detection range.

Two relays with closing contact (option) may be used for remote signalling or ventilation control. Default alarm set-points are 10 and 25 ppm. 

The device is available with either attached or remote sensor probe (default cable length is 3 m).
