DHM804 Digital Hydraulic Multimeter

The Webtec DHM804 is an all-in-one portable hydraulic flow meter / tester unit, based on best-selling DHT series, it measures flow, pressure, peak pressure, temperature, power and volumetric efficiency.

The DHM804 Digital Hydraulic Multimeter is an all-in-one unit designed to test the performance of hydraulic pumps, motors, valves and hydrostatic transmissions. The easy-to-use design allows the operator to just switch on and test, without complex setup. The DHM804 measures flow, pressure and temperature. In addition, the DHM holds the peak pressure value as well as calculating hydraulic power and volumetric efficiency using the unique P-Q test button.

The DHM804 is the ideal tool for pinpointing hydraulic system faults, reducing downtime, and helping in preventative maintenance. The design builds on the very successful DHT range of portable testers with the addition of a large digital display and a built-in pressure transducer. The turbine flowmeter with built-in loading valve is bi-directional and specifically designed to enable the operator to simulate the maximum working pressure safely during normal machine operation.

The loading valve has safety discs built-in to protect the operator and the multimeter in the event of excessive pressure, allowing oil to bypass the loading valve INTERNALLY with no spillage of oil from the hydraulic circuit, eliminating any danger to the operator or environmental hazards.
