TM 200

Cap Torque Tester


The TM 200 is a torque-measuring device specially designed to work on bottle caps.

Supplier: Sotax


  • Precise measurement of cap torque
  • Flexible bottle holder
  • Universal or custom-made cap adapters
  • Ideally suited for child-resistant closures

 The exact determination, especially of the opening torque, is a quality-defining factor. Use of the TM 200 provides reliable assurance and documentation that bottle caps have been closed with the appropriate amount of torque.

The TM 200 is either operated manually or motorized with the optional MDU2 motorized drive unit to ensure repeatable test conditions. It is controlled directly by the TM 200. Caps can be automatically opened and closed with constant and repeatable velocity thereby eliminating the inconsistencies that would otherwise occur with manual twisting. The TM 200 combined with MDU2 can also be utilized to place caps on bottles in small production runs.

The TM 200 principle of operation is based on the use of a proprietary load cell strain gauge. Reliable electronics measure and register the actual torque sensed and assures highest precision. The signals are monitored throughout the whole opening / closing procedure.

The maximum torque value attained is then displayed and stored. Alternatively, the TM 200 can also close the cap with a previously defined torque value.
