Description
Refrigerant detector E2630-HFC is an easy-to-use instrument intended for 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.
Two relays with switch-over contact may be used for remote signalling or ventilation control. Flashing LED and internal buzzer give visual and sound alarms.
