For determination of the needle penetration.
The penetration depth of the penetration needle is determined with an electronic position measuring system, which is decoupled from the plunger during the test. An influence on the load and friction is excluded, because of this the free guidance of the plunger.
The run-up and touch down of the needle are carried out automatically via the measurement system. Manual joystick mode is also possible. Then the plunger is enabled by an automatic device and blocked again after the testing period. The test result is displayed on the graphical touch display. The plunger can easily be removed to calibrate its weight.
- Measuring range: 0-300 (equivalent to 0-30 mm)
- Resolution: 0,01 mm
- Test load: 100 g (plunger 97.5 g + 2.5 g penetration needle)
- Test time: free (adjustable from 0,01 second)
