T6763 Series A2L Refrigerant Gas Sensor Module

Designed for OEM A2L Refrigerant Leak Detection Applications Requiring High Performance 

The Telaire T6763 Series A2L Refrigerant Sensors are ideal in applications where refrigerant gas levels need to be measured for leak detection and mitigation.

As an environmentally friendly alternative to past refrigerant types – and one that’s now required for many applications– A2L still poses many of the same risks as traditional hydrofluorocarbon (HFC) coolants, including flammability and toxicity at combustion. 

Using NDIR (non-dispersive infrared) technology, this sensor can monitor for & detect A2L refrigerant leaks the moment they start, providing an early warning and for fast intervention. 

All units are factory-calibrated to measure R32 refrigerant concentration levels up to 32500 PPM.
