Description

Ammonia detector-transmitter E2648-NH3-E is a member of new PluraSens® family of multifunctional measurement instruments.

The instrument is intended for leakage control in refrigeration facilities, warehouses etc. It is not recommended to use the detector in spaces with constantly high ammonia concentration such as cattle, pig and poultry livestock houses, since it shortens the sensor lifetime.   

The instrument utilises a fully calibrated and temperature compensated electrochemical 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.
