DHT 2 Series Bi-Directional Digital Hydraulic Tester


The DHT 2 Series Digital Hydraulic Tester accurately measures flow, pressure, temperature, and speed. The testers are designed for testing hydraulic pumps, motors, valves, and hydrostatic transmissions.

This easy-to-use diagnostic unit can pinpoint hydraulic system faults which reduces downtime and helps with preventive maintenance. The remote flow input can be easily configured by the operator for any LT/LTR flow block. The calibration is retained in permanent memory. The remote input feature allows main hydraulic circuits and drains leakage flows to be measured simply at the turn of a switch.

The tester comprises a turbine flow block and a large easy-to-read digital display that indicates both flow and temperature. Speed and remote flow are selected by a switch when required. The flow readout is scaled in LPM, GPM, and US GPM, selected by a push button.
