Product Description

1. HVAC gauges can test automobile air conditioning, household air conditioning, refrigeration equipment, cold storage and other refrigeration equipment.
2. Digital manifold gauge set built in 93 refrigerant pressure and temperature database so that can detect 93 kinds of refrigerants. 
3. HVAC manifold can perform refrigeration system pressure and temp. tests to determine refrigeration capacity.
4. Overheat/Subcooling Test&High/Low Pressure Temp. Test&Vacuum Operation
5. HVAC manifold supports multiple pressure&temperature unit switches, such as kPa,MPa,bar,InHg,PSI,Celsius/Fahrenheit.

3-color refrigerant hoses connection and valve operation method of Vacuum Test:

• Switch to the vacuum function, first press ZERO to reset the data to 0.
  
• Close blue valve tightly and do not connect any hoses to the corresponding inlet.
  
• Connect the vacuum pump to the vacuum pump inlet of the refrigerant gauge with the yellow hose.
  
• Open the red valve, connect the device under test with the corresponding red hose, and then you can start the vacuum operation.
  
  (Note: In the vacuum test, the blue valve does not work, only the red valve does. The blue valve needs to be closed. If the blue valve is not closed, the air pressure will escape from the blue valve and cause a leak, and the test data will be inaccurate.)
