Webster Testers are designed to conveniently check the performance of hydraulic pumps, motors, valves and hydrostatic transmissions.
This easy to use diagnostic tester has simplified controls and can pin point hydraulic system faults, reducing downtime and helping in preventive maintenance.
The tester comprises a turbine flow block and a large easy to read digital display which indicates both flow and temperature.
The tester has a built-in loading valve to simulate the working pressure during normal machine operation. The built-in safety discs protect the machine and operator in event of excessive pressure, allowing oil to safely bypass the loading valve INTERNALLY with no spillage of oil from the hydraulic circuit, eliminating clean-up costs and environmental hazards.

Operation
DHT testers are microprocessor-based instruments providing flexibility and high accuracy. Flow and Temperature are continuously
displayed in different sized fonts on a large liquid crystal display. Flow and temperature units can be changed with the display panel
buttons. Low power micro-circuitry and power management minimises battery consumption so a standard 9-volt battery, that is
available worldwide, will typically supply > 6 months normal testing.
The turbine block is made from high tensile aluminium and houses a six-blade turbine rotating on a stainless steel bearing and shaft.
Built-in flow straighteners reduce flow turbulence and allow accurate flow measurement in both directions.
The integral loading valve gives progressive pressure loading in either flow direction. Replaceable safety burst discs are part of
Interpass® safety protection system and operate if maximum pressure is exceeded, relieving flow to the return line. Replacement safety
discs are stored in an internal holder machined in the rear of the flow block.
There is an operational warning by a red LED if the electronics exceed maximum working temperature. This provides confidence in
readings when measuring fluids up to 125 °C (257 °F)

Service and Calibration
All digital hydraulic testers are calibrated at a mean viscosity of 21cSt using ISO32 hydraulic mineral oil to ISO11158 category HM.
Recommended period between services is 12 months. Maximum period between services is 36 months. Unit accuracy may be affected
by operating cycle, fluid condition or extended periods between services. Service reminders are displayed at power ON as a useful tool
to help keep the meter safe and working within specification.
Installation
It is recommended to connect the flow block with flexible hoses 1-2 metres (3-6ft) long. Inlet and outlet connections should always be
of a similar bore size to that of the flow block to prevent venturi or constriction effects.
Where repetitive pulsation causes lateral pipe movement against the ports, we recommend the hoses are firmly clamped.
Filtration
Must be better than DIN ISO4406: 21/19/16 or NAS 10 (typically achieved with 20-25u filters
