Digital Manifold HVAC Gauges Set with Pressure & Temp Test, Digital Refrigerant Gauges for R410A R22 R134A Built-in 89 Refrigerant Database, HVAC Gauges Set with Refrigerant Hoses,Temp Clips
[Multi-function HVAC Gauge]：The digital manifold HVAC gauge is an auxiliary instrument for the installation, testing and maintenance of refrigeration equipment such as air conditioners. The instrument has various functions such as dual pressure test, dual temperature test, digital readout, multi-unit switching and built-in refrigerant database. The digital manifold gauge adopts silicone anti-slip design on both sides to prevent slipping and comes with temperature clamps and refrigerant hoses.
[Pressure and Temperature Dual Test]：The HVAC gauges could operate dual pressure and temperature test to help you determine refrigeration capacity of refrigeration system. The lower the evaporation (Ev)/condensation (Co) pressure and temperature, the higher the efficiency of the refrigeration cycle and the higher the refrigeration capacity. HVAC gauges calculates the pressure difference between initial test pressure and the second test pressure to determine whether refrigerant is leaking.
[Built-in Refrigerant Database]：The digital manifold HVAC gauge has 93 built-in refrigerant pressure-evaporation temperature database. When temperature clamps are connected to air conditioning ducts which can calculate the subcooling degree and superheat degree, so that it is easy to read the operation process data directly. HVAC gauges also can be connected to a vacuum pump for vacuum operation, which makes the refrigerant filled with higher purity, the better the refrigeration effect.
[High-accuracy and Large LCD Display]：Digital manifold HVAC gauges set built-in 32-bit digital processing unit and high-accuracy data acquisition unit, supports multiple pressure&temperature unit switches, such as kPa, MPa, bar, InHg, PSI, Celsius/Fahrenheit, the data volume is high and stable. Large-size liquid crystal 3.5 inch display, LCD backlight support, convenient operation, and each test result is divided by lines on the screen, which making it easier and clearer to read your data.
[V-Shaped Valve Switch Designed]：Compared with other refrigerant gauges using ordinary knob valves, our digital refrigerant HVAC gauges use an upgraded V-shaped valve, which is a full-bore ball valve, with low fluid resistance and more accurate control of refrigerant charge, convenient to operate, which can easily open or close the valve by simply turning 90°, saving operation time. The valves are made of advanced materials that are corrosion, wear resistant, and can achieve complete sealing.
