Pressure Gauge Refrigeration Digital Vacuum Pressure Manifold Tester Air Conditioning Temperature T The instrument uses high-strength engineering plastics and flexible anti- 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. -size LCD display, backlight support, data display clear and easy to read, convenient light operation. Long-life valve-switch, 1/4-inch standard interface design to that the instrument's durability and versatility. Built-in 89 kinds of refrigerant pressure-evaporation temperature database, also calculate the subcooling superheat, to facilitate direct reading of operating process data. The intelligent electronic refrigerant 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 temperature test, digital readout, multi-unit switching, multi-mode function and built-in refrigerant database. It tests percentage of vacuum measurement; pressure leak measurement, leak time speed record. Multi-functional, accurate and simply operated digital manifold let you do the work right.
