Digital Manifold Gauge Refrigeration HVAC System Pressure Leakage Vacuum Tester. DUOYI522A 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. It is the best helper for air conditioning, refrigeration equipment and heat pump repair and maintenance.
THE VALVE SWITCH IS DESIGNED. The valve can be easily controlled, thus saving time from complicated knob operation. The amount of refilling refrigerant is easier to control than the refrigerant gauge using ordinary knob valves, which is convenient to operate and more durable.
BUILT-IN 93 KINDS OF REFRIGERANT NIST. According to the US NIST standard:R125. R218;R23;R124;R717;R21;R143A. R600;R123;R11;R12;R14;R13;R22. 3.5-INCH BACKLIT LED DISPLAY.
Each test result is divided by lines in the screen, making the data. More intuitive and clear at a glance.
REFRIGERANT SUBCOOL ING AND SUPERHEATING TEMPERATURE TEST. Temperature test range: -40150°C (-40-302°F). A variety of units are designed for your needs. The minimum pressure is when the refrigerant changes.From gas to liquid, and the maximum temperature is. When the gas changes to a liquid.
The minimum pressure when the refrigerant changes from gas to liquid. And the maximum temperature when the gas changes to liquid.
High-definition display: LED LCD large screen, which can be observed from multiple angles, and the data display is clear and intuitive. Multi-unit switching: 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.
