PH

Test bench for
hydraulic tools

4 torque ranges
from ± 0 - 3 kNm
up to ± 0 - 20 kNm

Suitable for

Adjusting and testing of hydraulic torque wrenches.
Inspection as per DIN EN ISO 9000ff.
Tabulating the relation of working pressure to torque.
Portable test bench.

With the model PH test bench it’s easy to adjust and test hydraulic tools; tabulate the relation of working pressure to torque; and check the performance of tools. Measurements can be displayed and documented with the supply and display unit GMV2. Tools with driving squares compliant with DIN 3121 can be plugged in directly. We supply a range of adapters for the different tools. Tools for hexagon bolts can be connected with various hexagonal adapters (refer to the “PH hexagonal adapters” specification sheet).
