HVAC Gauges Digital Manifold Gauges HVAC Manifold Gauge Set 92 Refrigerants AC Gauges Kit Test Pressure and Vacuum R410A Gauges R134A 1234YF R12 R404A R22 Refrigerant Gauges HVAC Refrigeration Gauges - CMTOOL, AQ-70

• 1.【92 Refrigerants & 5 Pressure Units & 2 Temperature 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. Pressure test and vacuum test units: kPa, MPa, bar, inHg, psi. temperature units: ℃ and ℉. 2.【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. 3.【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. 4.【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. 5.【Color Screen Display & Power Display & Low Power Reminder】The refrigerant gauges have a digital color 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. When the power prompt appears on the screen, it means that the power is low and the battery should be replaced in time. 6.【Packing List and 3-Year Warranty】The HVAC manifold gauge set includes a digital gauge, 3pcs refrigerant hoses with seals, 2pcs R134A quick connectors, a valve core remover, a universal can tap, an English manual, 3pcs 1.5V batteries, and a portable suitcase for you to keep and carry the ac manifold gauge set. We provide a 36-month free warranty for this digital manifold gauge set. If you have any questions about this a/c gauge set, please feel free to contact us.
