Refrigerant Manifold Pressure Tester Vacuum Temperature HVAC Digital Gauge Set. AUTOOL LM150 ball valve type intelligent electronic refrigerant meter, the high and low pressure valve adopts V-shaped opening design, which can accurately control the opening or closing of the valve, with good flow adjustment function, convenient operation, accurate test and longer service life.The instrument has the functions of pressure test, temperature test, refrigerant filling, vacuuming, pressure leak test and built-in NIST standard database of 93 kinds of refrigerants. LED LCD large screen, which can be observed from multiple angles, and the data display is clear and intuitive. Automatic conversion of pressure multi-unit, automatic conversion of temperature Celsius / Fahrenheit. Energy saving and environmental protection.
The meter has a micro power consumption design, and the battery life is longer. [V-shaped ball valve switch design]. LM150 high and low pressure valve adopts V-shaped opening design, which can easily control the valve switch, eliminating the tedious knob action, the amount of refrigerant added is easier to control than the ordinary knob valve refrigerant meter, and the operation is convenient and durable. The 3.5-inch backlit LED display can support dark environments and night operations.
Each test result is divided by lines in the display, and the data is more intuitive and clear at a glance. Built-in 93 NIST standard refrigerant databases. Can calculate supercooling and superheating, accurate dual-channel pressure and dual-channel temperature measurement, and vacuum percentage, pressure leakage measurement, leakage time speed record, automatic unit conversion and other functions.
The DY 522A becomes the tool for every HVAC job. The two wired temperature clamp probes included in the kit enable real-time evaporator and condenser measurements. The minimum pressure when the refrigerant changes from gas to liquid, and the maximum temperature when the gas changes to liquid. Calculate the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking.
