The hydraulic tester can accurately measure the flow, pressure and temperature. It is widely used for testing and diagnosing hydraulic pumps, motors, valves and hydrostatic transmission devices. It is characterized by simple use, simple control, accurate diagnosis of hydraulic system fault points, thus reducing downtime and contributing to preventive maintenance.

For a long time, the performance parameter detection of hydraulic system is similar to a closed black box problem, and it is impossible to directly observe the fluid parameters of hydraulic system. The hydraulic tester is a device that collects the data of the hydraulic system through the flow, pressure and temperature sensors, and displays the flow, pressure and temperature values after signal conditioning and A/D conversion.
