DescriptionThe DHM accurately measures flow, pressure and temperature and presents results in numeric and graphical formats. It is designed to test the performance of hydraulic pumps, motors, valves and hydrostatic transmissions, and to pre-set flow and pressure before fitting attachments on machines.
Main featuresAdvanced functions include display of power and volumetric efficiency to speed up fault diagnosis. The TrueFlow® direction indicator clearly shows flow direction. Fast capture of pressure peaks records very short spikes. Quick bar-graph views highlight fluctuations. Remote display via a mobile phone allows viewing DHM measurements while working near equipment.
App and data managementThe QuickCert®+ app (iPhone® and Android™ compatible) retrieves recorded data and generates actionable reports. The multilingual app simplifies report creation and export of records for quality and maintenance documentation.
Safety, sealing and calibrationAll DHM units include the Webtec charge valve with integrated Interpass® safety protection (internal bypass on overpressure). Devices are sealed against dust and water jets, supplied with a traceable calibration certificate and covered by a standard five-year warranty.
