Fieldpiece SSX34 Superheat and Subcooling Meter - NEW! Most non-electrical HVACR problems are charge related. Many systems in operation are undercharged or overcharged.

UEI SSM1 Superheat and Subcooling for 4 refrigerant. Use the SSM1 to directly measure superheat or subcool by direct connections for temperature and pressure. The SSM1 is programmed with the most common four refrigerants, with data from the NIST-Pro refrige

Overview for Fieldpiece SSX34The Fieldpiece Superheat amp; Subcooling for Air Conditioning & Refrigeration meter, model SSX34, measures suction line, or low side, line temperature and pressure. It then calculates actual superheat in real time using built-in P/T charts. It also measures liquid line, or high side, line temperature and pressure, and calculates actual subcooling.

Thermostatic Expansion Valves (TXVs) are a requirement for 14 SEER or higher split system heat pumps, and an optional upgrade for other air conditioning systems. Your system will operate more precisely and with greater efficiency with a TXV. These valves offer more control over how much liquid refrigerant enters the evaporator coil.
