Visualisation window observation and multi-unit switching and hook design: Manifold gauge set is equipped with a viewing window to keep an eye on the refrigerant filling status. During pressure and temperature testing, you can freely switch between pressure and temperature units, including kPa, MPa, bar, inHg, PSI, and switch the temperature unit between Celsius/Fahrenheit. The hook design of the hvac gauges allows you to perform the testing and other operations with ease and effort
Vacuum sealing and pressure leak/air tightness test: the pressure gauge can be connected to a vacuum pump to vacuum the cooling system. If the vacuum is approx. 90% and does not increase further, vacuuming is complete. After completion of the vacuum, the mode can be switched to leak test. By observing the pressure difference, it can be determined whether there is a leakage in the pipeline of the cooling system, and the duration of the leak test can be recorded
Intelligent multifunctional digital distributor measuring device set: our digital installer aid air conditioning set is versatile and has functions such as refrigerant filling, double pressure test, vacuation, air tightness test, multi-unit circuit, multi-mode functions and built-in refrigerant database, suitable for air conditioning installation and maintenance, daily maintenance of refrigerators, daily inspection of refrigeration warehouses and automotive equipment. air artung, etc
High-strength engineering plastic & 1/4 inch standard interface & TFT LCD display: digital hvac manifold pressure gauge set is made of high-strength engineering plastic, the whole machine is solid and comfortable to hold. It uses a large format TFT liquid crystal display and supports backlight, making it easy to read data even in dimly lit or dark environments. The 1/4" standard interface ensures the durability and versatility of the device
Double pressure test and display of condensation/evaporation temperature: During the refrigerant filling process, the digital meter hvac automatically calculates the pressure value of the refrigerant in the low pressure line (condensation pressure) and the pressure value of the high pressure line (evaporation pressure). At the same time, the corresponding condensation/evaporation temperature is calculated and displayed to ensure a reliable Basis for the Beurdivision of the operating status of the cooling system
Built-in 92 types of refrigerant data and 32-bit digital processing unit: digital HVAC measuring devices Hvac built-in 92 types of refrigerant pressure evaporation temperature database, and you can change or fill different types of refrigerants as needed, which is suitable for a variety of maintenance occasions. Built-in 32-bit digital processing unit and high-precision data acquisition unit, with high data and high stability characteristics, making the print data measurement more stable and accurate

Visualisation window and large LCD display: the digital manifold gauge set with clear glass viewing window for easy visualisation of the refrigerant level and easy operation. The large 2.5" backlit display is very easy to read even in low light conditions. We offer a 12-month free warranty and 24-hour customer service to ensure your shopping experience.
Test liquefaction/evaporation temperatures and pressures: Connect the temperature measuring clamps to the distribution meter, and the temperature sensors automatically measure the temperature (T1 sensor, T2 sensor) and check the condensing and evaporation temperatures and pressures of the refrigerant.
Refrigerant assembly aid suitable for 93 refrigerants: the air conditioning pressure gauge is suitable for testing a wide range of 93 refrigerants according to the US NIST standard. The pressure gauge set features a double pressure test, double temperature test, digital display, switching between different units (kPa, Mpa, bar, inHg, PSI or °C, °F) and a multi-mode function.
Pressure leak test and vacuum operation: the refrigerant assembly aid calculates the pressure difference between the initial test pressure and the second test pressure to determine whether the refrigerant is leaking. Note: when the AC pressure gauge is turned on, 10 digits may appear in the range of the high and low pressure indicator. At this time, long press the zero button until it returns to zero.
Automatic calculation of hypothermia and overheating: the air conditioning mounting aid gauge set has a digital 32-bit processing unit and a highly precise data acquisition unit, high data and stability. A digital manifold gauge can also calculate the degree of hypothermia and overheating, which is convenient to read the data directly during operation. In addition, the pressure gauge tests the percentage of vacuum measurement; pressure leak measurement and leak time recording

Versatile and user-friendly The HVAC/R instrument has an integrated database with 88 types of refrigerant pressure evaporation temperature data. With a large LCD display, a 2-way valve block with three ports and a hanging hook, it is easy to use and convenient to use.
Robust and reliable: The pressure gauge set has been specially designed for harsh environments and offers reliable performance with its robust design and shockproof housing.
Pressure retention and temperature compensation: With the pressure hold test, you can detect leaks, while the temperature compensation compensates pressure fluctuations due to the ambient temperature to ensure accurate measurement results and avoid misinterpretations.
Overheating and hypothermia measurement: The instrument automatically measures overheating and hypothermia in real time to save you the manual calculation. Note: The vacuum values are based on an algorithm. For high precision, we recommend the VGW series.
High/low pressure and temperature measurement: Thanks to the highly sensitive sensors, the digital distributor records the pressure and temperature on the high and low pressure side as well as the evaporation and saturation temperature of the selected refrigerant.
