Description

Refrigerant transmitter E2618-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, R1234yf and similar.

For demanding applications, a NDIR sensor is available on request.

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.
