This digital hydraulic pressure gauge is designed for accurate pressure testing on hydraulic systems used with excavators, loaders, bulldozers, and other heavy equipment. It measures from 0 to 10000 PSI and 0 to 700 bar, with selectable units including Bar, PSI, MPa, and kgf/cm². The gauge features a backlit digital display, zero calibration, and peak hold for easier reading and testing. Its SUS304 stainless steel housing and silicone protective cover help resist impact, corrosion, dust, and water. The standard 1/4" NPT base entry makes it suitable for connecting to a wide range of test systems.
