R-32 refrigerant is emerging as an alternative refrigerant as the refrigerant regulations for global environmental protection have been strengthened recently. R-32 refrigerant has excellent thermodynamic performance and has a relatively low GWP (Global Warming Potential) of 675, so it is in the spotlight as an alternative refrigerant gas in many countries.

Since R-32 refrigerant gas is a slightly flammable gas, gas leak detection is essential. TES0704 sensor is suitable for low-concentration gas leak detection and alarm applications and is required for refrigerant gas leak detection in air conditioning/refrigeration systems (HVACR systems). It is an NDIR (non-dispersive infrared) optical gas sensor that is more accurate and has a longer lifespan than the traditional semiconductor type. It is also an ideal sensor for users who require high accuracy at low concentrations.
