Push-pull tester

Push-pull tester

The push-pull tester is used to verify the mechanical strength of wires and structural parts.

Other tools

Torque wrench + micrometer + caliper + impact tester + torque driver + gap gauge + Hygrothermograph

All these tools can be combined to verify the mechanical strength, as well as electric strength, e.g. tracking distance and electric clearance, of the structural/electronic elements.
