T3400-EVAL

T3400-EVAL is a refrigerant leak detection sensor evaluation kit that enables quick and easy operation of Telaire’s T3400 sensor through a standard PC interface. T3400 is a Telaire’s T3400 series refrigerant leak detection sensor that can identify refrigerant gas leaks by assessing the thermal conductivity of a specific gas mixture. In the event of a refrigerant discharge, the variation in refrigerant concentration in the air results in changes in the thermal conductivity of the gas mixture which can be measured by the micro TCD sensing element. As compared to competing detection technologies, thermal- conductivity-based detection offers the benefits of superior long-term reliability and resilience in harsh operating environments.
