The volumetric efficiency (internal leakage) of hydraulic pumps will increase with age. Consequently, to prevent unnecessary downtime it is vital to check the efficiency of hydraulic pumps on a routine schedule. The test kit needed to perform the test must be relatively easy to install, safe, and accurate. The DHM 4 Series Bi-Directional Digital Hydraulic Multimeter is perfect for the task. The unit offers precise flow, pressure, temperature, power, and volumetric efficiency readings in a compact configuration.

The DHM 4 Series Digital Hydraulic Multimeter is an all-in-one unit designed to test the performance of hydraulic pumps, motors, valves, and hydrostatic transmissions with the added benefit of Bluetooth functionality.
