• 1.【Built-in 93 Kinds of Refrigerant Database】The upgraded digital HVAC manifold gauge set has a built-in 93 refrigerant pressure-evaporating temperature database according to the America NIST standard. Newly added 4 refrigerant types: R438A, R448A, R449A, and R452A. The manifold gauge set has the double pressure test, dual temperature test, digital readout, multi-unit switching (kPa, Mpa, bar, inHg, PSI or °C, °F ), and multi-mode function. 2.【Automatic Calculation of Subcooling and Superheating】The refrigeration gauges built-in 32-bit digital processing unit and high-precision data acquisition unit, high data and stability. Digital refrigerant gauges can also calculate the supercooling and superheating degree, which is convenient to read the data directly during the operation. In addition, the ac manifold gauge set tests the percentage of vacuum measurement. pressure leak measurement, and leak time speed record. 3.【Visualization Window & Refrigerant Charging & Vacuum Operation】Through the window of HVAC digital gauges, the charging state of the refrigerant can be directly observed, which is more convenient to operate. The HVAC digital manifold gauge set can realize vacuum operation by connecting the refrigeration equipment and vacuum pump. Note: When the gauge is turned on, there may be 10 digits in the high and low-pressure display area. At this time, press the zero button long until it returns to zero. 4.【Pressure Leak Test】The manifold gauge calculates the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking. The digital HVAC manifold gauge set is specially used for the installation, testing and maintenance of refrigeration equipment such as air conditioners, refrigerators, and cold storage. 5.【Ball Valve Type Switch & LCD Display & Hook Design】The HVAC refrigerant gauge adopts high-strength engineering plastics and an anti-skid design, the whole gauge is sturdy and comfortable to hold. Large-size LCD display, support backlight, the displayed data is clear and easy to read, easy to operate even in low light. The new ball valve switch has more precise control and longer service life. The 1/4 inch standard interface design ensures the durability and universality of HVAC digital gauges. 6.【Packing List and 3-Year Warranty】The digital manifold gauge set includes a manifold gauge, 2pcs temperature clamps, 3pcs hoses, and hose seal fittings (air leak proof), and comes with a carry case for easy storage and portability of the manifold gauge set. We provide a 36-month free warranty and 24 hours friendly customer service to ensure your shopping experience. If you have any questions about this manifold gauge kit, please feel free to contact us.
