The intelligent electronic group instrument is an auxiliary instrument for the installation, testing and maintenance of refrigeration equipment such as air conditioners and cold storage. The instrument has double pressure test, dual test, digital readout, multi-unit switching, multi-mode function and built-in database. 

Feature:
The instrument uses high-strength plastics and flexible -slip silicone design, the whole machine is solid and comfortable to hold. 
Built-in 32-bit digital processing unit and high- data acquisition unit, high data and stability.
Large-size LCD display, backlight support, data display clear and easy to read, convenient operation.
Long- -switch, 1/4-inch standard interface design to ensure that the instrument's durability and versatility.
Built-in 89 kinds of pressure-evaporation database, also calculate the subcooling superheat, to facilitate direct reading of operating process data. 
It tests percentage of measurement; pressure leak measurement, leak speed record. 
Multi-functional, accurate and simply operated digital manifold let you do the work right.
