Feature
●【Suitable for All Refrigeration Equipment & Detects 93 Refrigerants & Data Partition 3.5" LCD Display】HVAC gauges can test automobile air conditioning, household air conditioning, refrigeration equipment, cold storage and other refrigeration equipment. Digital manifold gauge set built in 93 refrigerant pressure and temperature database so that can detect 93 kinds of refrigerants. Test data is divided into areas on the 3.5-inch large backlit LCD display, so that you can read the data at a glance.
●【Upgraded V-shaped Valve Switch】Compared with refrigerant gauge hvac using ordinary knob valve,our digital refrigerant gauges adopt upgraded V-shaped valves, which are full-bore ball valves, with low fluid resistance, and control the refrigerant filling amount more accurately.You only need to turn 90° to easily open or close the valve and save operating time.V-shaped valve has two sealing surfaces using advanced material,which is resistant to corrosion and wear, and can achieve complete sealing.
●【Evaporation/Condensation Pressure and Temp. Test & Pressure Leakage Test】HVAC manifold can perform refrigeration system pressure and temp. tests to determine refrigeration capacity. The lower the evaporation/condensation pressure and temperature, the higher the efficiency of the refrigeration cycle and the greater the refrigeration capacity. HVAC gauges calculates the pressure difference between the initial test pressure and the second test pressure to determine whether refrigerant is leaking.
●【Overheat/Subcooling Test&High/Low Pressure Temp. Test&Vacuum Operation】When temperature clamps connect to AC pipe,it will read superheat and supercooling automatically.The higher the superheat, the smaller the expansion valve opening (less refrigerant) can be determined.Refrigerant temp. in the high/low pressure pipes can also be tested. HVAC gauges can be connected to a vacuum pump for vacuum operation, which makes the refrigerant filled with higher purity, the better the refrigeration effect.
●【Multiple Unit&32-bit Digital Processing Unit&Observation Window&Non-slip Silicone Design】HVAC manifold supports multiple pressure&temperature unit switches, such as kPa,MPa,bar,InHg,PSI,Celsius/Fahrenheit.Built-in 32-bit digital processing unit, more stable data processing.Viewing window allows you to observe refrigerant charging state directly.Silicone non-slip design prevents slip and fall. Digital manifold gauge set comes with temperature clips and refrigerant hoses(burst pressure:3000 PSI)

Description
This HVAC gauge is for regular residential AC. It is suitable for all automobile air conditioner, household air conditioning, refrigeration equipment and cold storage, etc.
Specification:
Built-in 93 kinds of refrigerant NIST: According to American NIST standard
Power Supply: 4pcs * 1.5V AA / LR6 batteries (Battery not included)
Dimensions: 240*145*50mm
Weight: 950g
Question 1: How to verify the accuracy of the temperature?
Answer: Take out the black wire with the silver metal from 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. NOTE: Please pay attention to temperature unit conversion between Celsius/Fahrenheit.
Question 2: Does this gauge have a micron reading function?
Answer: No, the accuracy of this refrigerant manifold gauge can only reach the accuracy equivalent to this unit: -101 Kpa-0 Kpa.
Question 3: Why does the pressure value fluctuate slightly? Is it a leak or is the data inaccurate?
Answer: According 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.

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.)
WARMLY NOTE:
1. The temperature measured by the gauge is allowed to deviate by 3% from the actual temperature.
2. The HVAC guage will read random numbers when it is powered on. You must press the ZERO key to clear the numbers after you power it on.
Correct steps:
- Power it on, then close the two valves, press the ZERO key to clear the reading.
- Connect the three-color hoses, then open the valve, and use it normally.
3. The temperature probe of the temperature clamp is a silver metal part. When testing the temperature, the silver metal must be in full contact with the object to be measured, or you can take out the silver metal to measure the temperature to make the test temperature accurate.
4. Before 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.
5. Before use, please confirm the rated pressure value of the equipment under test.
The burst pressure of the refrigerant hoses is 3000 PSI.
