Features: Digital Manifold Gauge is suitable for car refrigeration, and air conditioner. Double pressure measure:,Digital Manometer Air Conditioning Tools are able to measure double pressure (gauge pressure) at the same time, as well as dual temperature measurement. Also Refrigeration Digital Manifold Gauge tests percentage of vacuum measurement; pressure leak measurement, leak time speed record. The Refrigeration Digital Manifold Gauge can measure double pressure at the same time, as well as dual temperature measurement, with automatic multi-unit pressure conversion, automatic conversion of temperature Celsius / Fahrenheit, to facilitate different needs. Built-in 32-bit digital processing unit and high-precision data acquisition unit, high data and stability. Large-size liquid crystal display, LCD backlight support, data display clear and easy to read, convenient light operation. The accurate and easy-to-operate digital manifold allows you to do the job correctly.
