Stress Measurement System

Medical connector measurement system “PT-1946MC”

Outline
“PT-1946MC” can perform fitting and torsion stress test specified in common test method of former ISO 594 and ISO 80369 Part 20.
Fitting and torsion stress test is performed by fixing the fitting gauge on the driving unit side and the medical connector on the torque sensor side and twisting while pressing the fitting gauge and the medical connector. Pressing is done by the electro-pneumatic regulator and the pressing load value is measured by the load cell. Torsion is done by the drive unit and the torsion torque is measured with the torque sensor.
