The New Flamefast Duct Refrigerant Sensor allows for accurate monitoring of a wide range of refrigerant gases from a single unit. Using highly stable infra-red technology and full temperature compensation on all gases, it can be used for detection, rather than just for alarm conditions like semi-conductor sensors.ccurate monitoring of a wide range of refrigerant sensors from a single unit.
 
To calibrate, only 1,000ppm R1234ze is required, then simply select your target gas from the calibration menu.
 
The full list of gases monitored is:
