Our digital HVAC manifold gauge set is versatile and has features such as refrigerant filling, dual pressure testing, vacuuming, air tightness testing, multi-unit switching, multi-mode functions, and built-in refrigerant database, suitable for air-conditioning installation and maintenance, daily maintenance of refrigerators, daily inspection of cold storage and automobile air-conditioning maintenance, etc.

Digital gauges hvac built-in 92 kinds of refrigerant pressure-evaporation temperature database, and you can switch or fill different types of refrigerants as needed, which is suitable for a variety of maintenance occasion. Built-in 32-bit digital processing unit and high-precision data acquisition unit, with high data and high stability characteristics, making the pressure data measurement more stable and accurate.

During the refrigerant filling process,digital gauges hvac will automatically calculate the pressure value of the refrigerant in the low-pressure pipe(condensation pressure) and the pressure value of the high-pressure pipe(evaporation pressure).At the same time,the corresponding condensation/evaporation temperature will be calculated and displayed to provide a reliable basis for judging the operating status of the refrigeration system.

Manifold gauge can be connected to a vacuum pump to perform vacuuming on the refrigeration system. When the vacuum reaches about 90% and will not continue to rise, the vacuuming is completed. After the vacuuming is completed, the mode can be adjusted to the leakage test state. By observing the pressure difference, it can be judged whether there is any leakage in the refrigeration system pipeline, and the duration of the leak test can be recorded.

Refrigeration gauges are designed with a visual window to keep an eye on the refrigerant filling status. During the pressure test and temperature test, you can freely switch between pressure units and temperature units, including kPa, MPa, bar, inHg, PSI, and temperature unit switching between Celsius/Fahrenheit. The hook design of the hvac gauges allows you to perform the test and other operations with ease and effort.

Digital hvac manifold gauge set is made of high-strength engineering plastic, the whole machine is solid and comfortable to hold. It uses a large-size TFT liquid crystal display and supports backlight display, making it easy to read data even in dimly lit or dark environments. 1/4-inch standard interface design ensures the durability and versatility of the instrument.
