Refrigerant detector-transmitter E2608-HFC is a member of new PluraSens® family of multifunctional measurement instruments.
Applications include cold storage warehouses, skating arenas, and other areas, where leakages of halocarbon refrigerants are possible.
The instrument utilises a fully calibrated metal-oxide semiconductor gas sensor with excellent repeatability, stability and long lifetime. The sensor is highly sensitive to a wide range of CFC, HFC and HFO compounds, including R-12, R-123, R-125, R-134a, R-143, R-22, R-404a, R-407c, R-410a, R-507, R-514a, R-1234yf, R-1234ze and similar.
For demanding applications, a NDIR sensor is available on request.
Two relays with closing contact may be used for remote signalling or ventilation 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.
