DUOYI 522A 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 intelligent digital display of the test results of the pressure and temperature of the air conditioning system reduces the cost of time. 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. V-shaped ball valve switch design. DUOYI522A 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 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. 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. 0.1°C (-40°C-99.9°C), 1°C (100°C-150°C) 0.1°F (-40°F-99.9°F), 1°F (100°F-302°F).
