Digital Manifold Gauge Set Pressure&Temp Test HVAC Manifold Pressure Leak Test Digital Refrigerant Gauges Vacuum HVAC Gauges with Refrigerant Hoses&Temperature Clamps&LCD Display for Air Conditioning

【Evaporation/Condensation Pressure and Temp Test&High/Low-pressure Temperature Test HVAC Manifold】The HVAC gauges could operate dual pressure and temperature test to help you determine refrigeration capacity of refrigeration system. The lower the pressure and temperature of the evaporation(Ev)/condensation(Co) are, the more efficient the refrigeration cycle and the greater the refrigeration capacity will do. It also could test the temperature of the refrigerant in the high/low-pressure pipes.
【Superheat and Subcooling Test&Pressure Leak Test】When refrigerant type is set and temperature clamps are connected to air conditioning pipes, HVAC gauges automatically read the degree of Superheat(SH) and Subcooling(SC). The higher the degree of superheat, the smaller the opening of the expansion valve (the refrigerant filling is less) can be determined. Calculate the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking.
【Vacuum Pumping & Refrigerant Filling & Built-in 89 kinds of Refrigerant Database HVAC Manifold】Digital manifold gauge set can connect refrigeration equipment and vacuum pump for vacuum pumping operation. Vacuum pumping can make it easier to fill the refrigerant into the pipeline. HVAC gauges is built-in 89 kinds of refrigerant pressure&temperature database. Before you fill refrigerant, you can set different types of working refrigerants according to the car needs to fill.
【Refrigerant Observation Window & Large LCD Digital Display & Multiple Unit Switching】When filling the refrigerant, you can observe the filling status of the refrigerant through the visible window. Equipped with large LCD display, clear data display and easy to read. You also can switch multiple pressure units, including kPa, Mpa, bar, inHg, PSI, along with the temperature unit switch between Celsius/Fahrenheit. Besides,it is equipped with refrigerant hoses and temperature clamps for better use.
【High Data Stability & Wide Application HVAC Gauge】Built-in 32-bit digital processing unit and high-precision data acquisition unit make it have high data stability. It uses high-strength engineering plastics and a flexible non-slip silicone design, sturdy and durable. Digital refrigerant Gauge is an auxiliary instrument for the installation, testing and maintenance of refrigeration machines such as automobile air conditioner, household air conditioning, refrigeration equipment and cold storage.
