The large 2.5" backlit display is very easy to read even in low light conditions. We offer a 12-month free warranty and 24-hour customer service to ensure your shopping experience.
Test liquefaction/evaporation temperatures and pressures: Connect the temperature measuring clamps to the distribution meter, and the temperature sensors automatically measure the temperature (T1 sensor, T2 sensor) and check the condensing and evaporation temperatures and pressures of the refrigerant.
Refrigerant assembly aid suitable for 93 refrigerants: the air conditioning pressure gauge is suitable for testing a wide range of 93 refrigerants according to the US NIST standard. The pressure gauge set features a double pressure test, double temperature test, digital display, switching between different units (kPa, Mpa, bar, inHg, PSI or °C, °F) and a multi-mode function.
Pressure leak test and vacuum operation: the refrigerant assembly aid calculates the pressure difference between the initial test pressure and the second test pressure to determine whether the refrigerant is leaking. Note: when the AC pressure gauge is turned on, 10 digits may appear in the range of the high and low pressure indicator. At this time, long press the zero button until it returns to zero.
Automatic calculation of hypothermia and overheating: the air conditioning mounting aid gauge set has a digital 32-bit processing unit and a highly precise data acquisition unit, high data and stability. A digital manifold gauge can also calculate the degree of hypothermia and overheating, which is convenient to read the data directly during operation.
