HVAC Digital Manifold Gauge Set for 92 Refrigerant Digital HVAC Gauges Pressure&Temp Test R134A R410A R404A R22 Refrigerant Gauges with Hoses, Upgraded Ball Valve,for Air Conditioning & Refrigeration

【Suitable for All Refrigeration Equipment & Detects 92 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 92 refrigerant pressure and temperature database so that can detect 92 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 test 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)

【Warmly Note】When the HVAC guage is turned on, it will read random numbers (there may be 10 digits in the high and low pressure display area). You must press the ZERO key to clear numbers after power it on. If you use it directly without pressing the ZERO key, the measurement will be inaccurate.
