Refrigerant Gas Sensor HCF100

The HCF100 is a Refrigerant Gas sensor for connection to Duomo gas detector controllers. Using semiconductor technology to detect the presence of a large range of Freons including R134a, R404A, R407C, R410A as well as NH3 Ammonia. A popular feature of the HCF100 is its ability to auto calibrate under varying conditions which minimises false alarms.

The HCF100 Refrigerant gas sensor is for detection of refrigerant gases including a large range of Freons & Ammonia. An industry standard 4-20mA signal output proportional to concentration of gas in air. The sensor is powered by and sends a signal back to, a Duomo gas detector panel. The detector then interprets the signal and is capable of sounding alarms and turning off appliances in the protected area.

The detector can run self diagnostics and automatically calibrates the sensor when ambient conditions vary minimising false alarms. Because of these features the HCF100 has become our most popular sensor product.

A hand-held datalogger can be connected to the HCF100 and information about the sensor can be read and printed out i.e.:
