DUOYI DY517 Refrigeration Digital Manifold Gauge Meter HVAC Vacuum Pressure Temperature Tester Leakage Test

Description

The intelligent electronic refrigerant group instrument is an auxiliary instrument for the installation, testing and maintenance of refrigeration equipment such as air conditioners,fridge 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. 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.

Because of the reading instability it was difficult to diagnose if the manifold itself has leaks. Too bad, because it looks like a nice mechanical design. I am pretty sure that if the manufacturer improves on electronics stability and keeps the price close to the current one, this could become a very competitive product. This is the second item I purchased from a different seller, but it seems that this manifold is sourced from the same manufacturer.
