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.
