Meterk Pressure Gauge Refrigeration Digital Vacuum Pressure Manifold Tester Meter HVAC Temperature Tester Digital Manifold Gauge Meter HVAC Vacuum Pressure

The instrument can measure double pressure (gauge pressure) at the same time, as well as dualtemperature measurement (need test clip,not include), with automatic multi-unit pressure conversion,automatic conversion of temperature Celsius / Fahrenheit, to facilitate different needs. Built-in 89 kinds of refrigerant pressure-evaporation temperature database, also calculate thesubcooling superheat, to facilitate direct reading of operating process data. Also it tests percentag
