Ammonia Detector-Transmitter

  • Stable long-life metal-oxide sensor
  • Range 0...1000 ppm NH3
  • Resolution 1 ppm NH3
  • Two SPST relays
  • 2 × 4-20 mA or 0-10 V, RS485


Ammonia detector E2611-NH3 is a member of new PluraSens® family of multifunctional measurement instruments which is intended for detection of ammonia gas emissions in agriculture and refrigeration industries. 

Applications include poultry, dairy, cattle  farms, industrial refrigerators, where potentially dangerous concentration of NH3 can accumulate.

The instrument utilises a fully calibrated metal-oxide semiconductor gas sensor with excellent repeatability, stability and long lifetime.

Two relays with closing contact may be used for remote signalling or ventilation control. Two alarm set-points are user settable. Internal buzzer gives sound alarms.

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.
