Weight: 6.31 lb Item Description ?Intelligent HVAC Gauges?This digital manifold gauge set hvac integrates multiple functions such as dual pressure test, vacuum pressure test, evaporation (Ev)/condensation (Co) temperature display, pressure leak test, vacuum operation, refrigerant filling, multi-unit conversion, built-in 92 refrigerant database, etc. It can be widely used in the installation, inspection and maintenance of all refrigeration equipment such as household/automotive air conditioners, cold storage and refrigerators. ?92 Kinds of Refrigerant Detection High Performance Chip?Our digital refrigerant gauges hvac has built-in 92 kinds of refrigerant pressure and temperature database for selection to meet your different needs. The digital gauges hvac adopts a 32-bit digital processing unit and a high-precision data acquisition unit, providing higher accuracy and stability. ?Dual Pressure Test with Co/Ev Temperature Display Refrigerant Filling?The digital manifold gauges hvac can test high and low pressure at the same time (pressure test range: 0~870psi) and display the corresponding condensation and evaporation temperatures under the corresponding pressures, helping you determine the operating status of the refrigeration system and the filling of refrigerant. ?Vacuum Pressure Test Vacuum Operation?The R22 R134A R410A R1234YF refrigerant recharge kit can be connected to the refrigeration equipment and the air compressor for vacuum operation, and the vacuum degree and pressure value can be displayed in real time(Vacuum test range: -14.65psi~0psi). The vacuum operation reduces the impurities in the refrigeration equipment, the higher the purity of the filled refrigerant, and the better the refrigeration effect. ?Pressure Leak Test?This ac gauges set can calculate the pressure difference between the initial test pressure and the second test pressure to determine whether there is a leak in the refrigeration system pipeline, and also can record the duration of the leak. ?Multi-unit Conversion TFT Color Display?The digital refrigerant meter hvac supports free switching of multiple pressure units and temperature units, including PSI, kPa, MPa, bar, inHg, ?, ?. Our hvac gauges have a large-size TFT color screen with backlight, so you can read the data clearly even in low light or dark environments. The data partition display is more intuitive. ?Refrigerant Observation Window 1/4 inch Standard Interface?You can observe the flow of refrigerant and the generation of condensed water in real time through the visual refrigerant filling window, so as to determine whether the refrigeration system is operating normally. The 1/4 inch standard interface is made of high-quality metal material, which is corrosion-resistant, not easy to deform, and has high sealing performance. ?Pressure-resistant 3-color Hoses Hook Design High-strength Engineering Plastic Shell?3-color hoses are made of durable rubber, which is resistant to pressure, high temperature and aging. Its max working pressure is 600PSI,and the max bursting force is up to 3000PSI. It is equipped with a hook that allows you to hang it on the car without holding it all the time, which is convenient for operation.The sturdy shell of high-strength engineering plastic ensures the durability of the hvac gauge. ?3-Year Warranty Packing List?We aim at trying our best to offer you the best product and services to make you unworried before/after the purchase. We promise a 3-year warranty. Package includes: 1* Main unit; 1* Bottle opener; 1* Valve core wrench; 2* Quick connector; 3* 1.5m Three-color hose; 4* Seal fittings; 1* Suitcase; 1* Instruction manual.

Product Description Pressure test unit: Kpa; Mpa; bar; inHg; PSI Pressure test range: 0 Kpa-6000 Kpa; Pressure test resolution: 1 Kpa Pressure test accuracy: +/-0.5 %(FS)+5dgt Pressure overload limit: 10000 Kpa (10 Mpa; 100 bar) Vacuum test: relative vacuum Vacuum test unit: Kpa; Mpa; bar; inHg; PSI. Vacuum test range: -101 Kpa-0 Kpa Vacuum test resolution: 1 Kpa Dual Pressure Test with Co/Ev Temp Display Test high and low pressure at the same time and display the corresponding condensation and evaporation temperatures under the corresponding pressures, helping you determine the operating status of the refrigeration system and the filling of refrigerant. Vacuum Operation HVAC gauges can connect to refrigeration equipment and air compressor for vacuum operation, so that the purity of the added refrigerant becomes higher and the cooling effect is better. Pressure Leak Test Calculate the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking, and can record the duration of the leak. Multi-unit Conversion 2.4" TFT Color Display Equipped with a TFT color screen with backlight, allowing you read the data clearly even in low light or dark environments. Data partition display is more intuitive. Power Supply: 3pcs 1.5V AA/LR6 batteries (not included) Dimensions: 165*110*60mm Weight: 800g Return Policy ?
