Ammonia detector-transmitter E2638-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 relays with closing contact (optional) may be used for remote signalling or concentration control. Two alarm set-points are user settable.
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.
