Instruction:

instrument for the installation, testing and maintenance of refrigeration equipment such as air conditioners and cold storage.
The instrument has double pressure test, dual temperature test （need test clip）.Note: DY517 does not include the test clip (need to be purchased separately).
And digital readout, multi-unit switching, multi-mode function and built-in refrigerant database.
The instrument uses high-strength engineering plastics and flexible non-slip silicone design, the whole machine is solid and comfortable to hold. 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.
Long-life valve switch, 1/4-inch standard interface design to ensure that the instrument's durability and versatility.

The intelligent electronic refrigerant group instrument is an auxiliary

The instrument can measure double pressure (gauge 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 89 kinds of refrigerant pressure-evaporation temperature database, also calculate the subcooling superheat, to facilitate direct reading of operating process data.
Also it tests percentage of vacuum measurement; pressure leak measurement, leak time speed record. It is deserved to have this multi-functional, accurate and simply operated digital manifold let you do the job right.
