DHT Series Bi-Directional Digital Hydraulic Tester


The new and improved DHT Digital Hydraulic Tester accurately measures oil flow, pressure, and temperature and has a built-in loading valve to simulate the working pressure during normal machine operation. The tester is ideal for reactive, proactive, and preventive maintenance, designed to conveniently check the performance of hydraulic pumps, motors, valves, and hydrostatic transmissions as well as the setup of hydraulic attachments such as hammers and breakers.

Hydraulic pumps are prone to experiencing internal leakage as they age, which can result in decreased volumetric efficiency. As such, it is imperative to perform routine checks to ensure the pumps are operating at optimal levels and minimize downtime. To facilitate this task, it is recommended that you use a digital hydraulic tester that is both safe and accurate. The DHT Series Digital Hydraulic Tester is specifically designed for this purpose and boasts an array of features that make it a valuable diagnostic tool. This user-friendly tester incorporates a turbine flow block and an easy-to-read digital display that shows flow and temperature readings.

The DHT Series Digital Hydraulic Tester comes equipped with simplified controls that facilitate quick and efficient identification of hydraulic system faults. The unit now offers selectable flow and temperature and has an IP65 rating. The unit also has low power consumption and operates off of a standard 9-volt battery. All DHTs come with a five-year warranty as standard.
