DUOYI522A ball valve intelligent electronic refrigerant table, high and low pressure valve with V-shaped opening design, can accurately control the valve open or close, with good flow regulation function, easy to operate, accurate test, longer service life. With pressure testing, temperature testing, refrigerant filling, vacuuming, pressure and leakage testing, and NIST standard database of 93 types of refrigerant, the meter is the best helper for air conditioning, refrigeration equipment and heat pump repair and maintenance.V-shape ball valve switch design? DUOYI522A high and low pressure valve using V-shaped opening design can easily control the valve switch, save cumbersome knob action, filling refrigeration dose than ordinary knob valve refrigerant table is easier to control, easy to operate more durable. The 3.5-inch backlit LED display can support dark environment and night operation.
The display uses lines to divide each test result, making the data more intuitive and clear at a glance. With 93 NIST standard refrigerant databases, the ability to calculate supercool and superheat, accurate two-channel pressure and temperature measurements, as well as vacuum percentage, pressure leakage measurement, leakage time velocity recording, automatic unit conversion and other features make the DUOYI522A a tool for every HVAC job. Two wired temperature clamp probes are included in the kit for real-time evaporator and condenser measurements. HD display: LED LCD large screen, can be observed from multiple angles, data display is clear and intuitive.Multi-unit switch: Automatic conversion of pressure multi-unit, automatic conversion of temperature in Celsius/Fahrenheit. Energy saving and environmental protection: The meter has a micro-power consumption design, and the battery life is longer.
