The digital manifold HVAC gauge is used to assist in the installation, testing and maintenance of refrigeration equipment such as air-conditioning and cold storage.

It has outstanding features such as dual pressure test, dual temperature test function, digital reading, multi-unit switching, and built-in refrigerant database.

Note: The temperature measured by the device is allowed to have a deviation of 3% from the actual temperature.

Digital manifold gauge set HVAC has a built-in database of 89 refrigerant pressure-evaporation temperature.

Before you fill refrigerant, you can set different types of works with R410a, R22, and R134a ect.

refrigerants according to the car needs to fill.

Digital manifold gauge set can also calculate the degree of subcooling and superheating.

It also can tests the percentage of vacuum measurement,pressure leak measurement.
