3. Digital Manifold Gauge Set Pressure&Temp Test HVAC Manifold Pressure Leak Test Digital Refrigerant
- Evaporation/Condensation Pressure and Temp Test&High/Low-pressure Temperature Test HVAC ManifoldThe HVAC gauges could operate dual pressure and temperature test to help you determine refrigeration capacity of refrigeration system. The lower the pressure and temperature of the evaporation(Ev)/condensation(Co) are, the more efficient the refrigeration cycle and the greater the refrigeration capacity will do. It also could test the temperature of the refrigerant in the high/low-pressure pipes.
- Superheat and Subcooling Test&Pressure Leak TestWhen refrigerant type is set and temperature clamps are connected to air conditioningpipes, HVAC gauges automatically read the degree of Superheat(SH) and Subcooling(SC). The higher the degree of superheat, the smaller the opening of the expansion valve (the refrigerant filling is less) can be determined. Calculate the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking.
- Vacuum Pumping & Refrigerant Filling & Built-in 89 kinds of Refrigerant Database HVAC ManifoldDigital manifold gauge set can connect refrigeration equipment and vacuum pump for vacuum pumping operation. Vacuum pumping can make it easier to fill the refrigerant into the pipeline. HVAC gauges is built-in 89 kinds of refrigerant pressure&temperature database. Before you fill refrigerant, you can set different types of working refrigerants according to the car needs to fill.

Equipped with a hook that allows you to hang the gauge on the car without holding it all the time. Besides, it is equipped with refrigerant hoses and temperature sensor clamps for better use. Connect the temperature clamp to measure the temperature. The burst pressure of the hose set is 3000 PSI.
- How to Verify The Accuracy of The TemperatureThe temperature measured by the HVAC gauge is allowed to deviate by 3% from the actual temperature. There is a simple way to verify the accuracy of the temperature: Take out the black wire on the temperature clamp and put it in the boiling water. If the temperature is 100 degrees Celsius or the error is plus or minus 3%, it is normal.
- NoteAccording to the current level of hardware processing in the industry, it is difficult to achieve a 100% completely sealed valve on the market. The sealing degree of our guage hardware can only reach 99%. But these slight leaks will not affect the use.
- Warmly NoteBefore using the HVAC guage, please make sure that refrigerant hoses and temperature sensor clamps are connected properly. Poor connection of the temperature sensor clamps will make it impossible to read the temperature. Poor connection of the refrigerant hoses will cause refrigerant leakage.
