WEBTEC DHT401 Manuel D'utilisation D'origine page 3

Webtec Portable Hydraulic Testers have been designed for easy connection to a hydraulic
circuit so that flow, pressure and temperature can be readily checked. Testers can take full
back pressure up to 210/420/480 bar (3000/6000/7000 psi) depending on the model, and the
built in loading valve enables many of the operating conditions to be simulated. The tester can
be connected anywhere in the hydraulic system to test pumps, motors, valves and cylinders
in both flow directions.
The tester range consists of the following types:
DHT 1 Series Digital Hydraulic Tester
l
HT 2 Series Analogue Hydraulic Tester
