Description
Ammonia transmitter E2618-NH3-P is a member of the PluraSens® family of multifunctional measurement instruments.
One of the most common applications is detection of explosive Ammonia concentrations in refrigeration machinery rooms.
The instrument utilizes a fully calibrated and temperature compensated pellistor (catalytic) 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.
