Weight: 2.0 lb ?92 Refrigerants 5 Pressure Units?This digital refrigerant gauge has a 92 refrigerant database suitable for various maintenance occasions, and a built-in 32-bit digital processing unit to ensure data stability and accuracy. The HVAC manifold gauge set supports the automatic conversion of multiple units and is easy to operate. ?Double Pressure Test, Calculation Evaporation and Condensation Temperature?The HVAC gauges can measure the pressure of low-pressure pipelines and high-pressure pipelines at the same time. The pressure test range is 0-6000Kpa, and the pressure overload limit is 10000Kpa. The air conditioning gauges automatically calculate the evaporation and condensation temperature (saturation temperature under evaporation and condensation pressure) according to the pressure value. ?Pressure Leak Test Zeroing Data?The digital HVAC gauges can record the initial pressure value and the instantaneous pressure value, and can also automatically calculate their pressure difference. It can also display the time of the leak test in the format of "hours: minutes" (HH:MM). When the HVAC digital manifold gauges are turned on, there may be 10 digits in the high and low pressure display area. At this time, you can press and hold the "ZERO" button to return to zero. ?Refrigerant Filling Vacuum Operation Standard Interface?This HVAC gauge can easily add refrigerant to the refrigerant system, and can also be used with a vacuum pump for vacuum operation. When the vacuum degree on the screen reaches about 80%-90% and is stable and no longer changes, the vacuum is completed. The HVAC manifold gauge has a portable hook, a visual window and a sturdy valve switch. The 1/4-inch standard interface is made of metal, which is corrosion-resistant and more durable. ?HD Screen Display Power Display?The refrigerant gauges have a HD digital display screen, support backlight display, and the data is clear and easy to read, which is convenient for operation in low light. The HVAC gauge is powered by 3 1.5V batteries (included in the package), and the battery power is displayed in the upper right corner of the screen.
