Refrigeration Digital Manifold Gauge Meter HVAC Vacuum Pressure Temp Tester. AUTOOL LM120+ Digital Manifold Gauge. Is an auxiliary instrument for the installation, testing and maintenance of refrigeration equipment such as air conditioners, fridge and cold storage. The instrument has double pressure test, dual temperature test, digital readout, multi-unit switching, multi-mode function and built-in refrigerant database. Evaporation Pressure & Temperature Test.
The maximum pressure when the refrigerant changes from liquid to gas. The lowest temperature when the liquid becomes gaseous. The lower the pressure and temperature of the evaporation are, the more efficient the refrigeration cycle and the greater the refrigeration capacity will do.Condensing Pressure & Temperature Test. The minimum pressure when the refrigerant changes from gas to liquid, and the maximum temperature when the gas changes to liquid. The lower the pressure and temp of condensation are, the higher the efficiency of the refrigeration cycle and the greater the refrigerant capacity will do. High / Low-Pressure Temperature Test. The temperature of the refrigerant in the high / low-pressure pipelines of the air conditioning system. Calculate the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking.
The instrument can measure double pressure at the same time, as well as dual temperature measurement, with automatic multi-unit pressure conversion, automatic conversion of temperature Celsius / Fahrenheit, to facilitate different needs. Built-in 32-bit digital processing unit and high-precision data acquisition unit, high data and stability. Large-size liquid crystal display, LCD backlight support, data display clear and easy to read, convenient light operation. Long-life valve switch, 1/4-inch standard interface design to ensure that the instrument's durability and versatility.
