The newest DHM series gives digital readouts of flow rate, fluid temperature, pressure, peak pressure, volumetric efficiency and hydraulic horsepower. It comes in ranges up to 250F, 100 gpm, 200 gpm, and peak pressure up to 9,000 psi. The multimeters feature the InterPass safety disc system, which guards the operator, hydraulic system, and the environment against external loss of high-pressure fluid. They also allow testing for setting and verifying relief valves, component leak testing and automatic calculation of pump volumetric efficiency. Webster is offering a free DVD describing this new series.
