Hydraulic pumps experience decreased volumetric efficiency due to internal leakage as they age. To prevent costly downtime, it is essential to check hydraulic pump efficiency on a regular basis using a test kit that is safe, accurate, and easy to install. The DHM 4 Series Bi-Directional Digital Hydraulic Multimeter is a versatile unit that can accurately measure hydraulic flow, pressure, peak pressure, temperature, power, and volumetric efficiency.

The DHM 4 Series Digital Hydraulic Multimeter is a next-generation diagnostic tool that offers Bluetooth functionality and is designed for hydraulic field service engineers. This all-in-one tester allows users to measure the true performance of their hydraulic system, quickly pinpoint faults, and generate and email a test report using the free-to-download Webtec QuickCert™ App and Smart Bluetooth™ functionality. Its portable design means you can use it on the factory floor, at a mine, in a quarry, or at a construction site, without having to return to the office to send a report.

The DHM 4 Series Digital Hydraulic Multimeter features onboard memory to record a simple 12-point test, making it easy to characterize a hydraulic pump’s performance at varying pressures using the built-in loading valve with Interpass™ safety system. This diagnostic tool is an ideal solution for reducing downtime and helping with preventive maintenance by pinpointing hydraulic system faults.
