Ammonia Transmitter E2618-NH3-S

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


Ammonia transmitter E2618-NH3-S is a member of new PluraSens® family of multifunctional measurement instruments.

Applications include refrigeration facilities and animal agriculture (cattle, pig and poultry livestock houses).

The instrument utilises a fully calibrated and humidity compensated metal-oxide semiconductor 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.
