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:

- R404a	- R407f	- R227
- R134a	- R1234yf	- R22
- R125	- R449a	- R513a
- R407a	- R507	- R422d
- R417a	- R123	- R1233zd
- R448a	- R410a	- R407c
- R32	- R452b	- R1234ze

With a BACnet MS/TP interface, a 0-10V and relay output, the refrigerant sensor in one of the most versatile units available, all housed in a robust duct enclosure for monitoring supply or return air systems.
