Digital Cap Torque Tester for PET Bottle Closures

Torque meter that measures application and removal torque of screw caps on PET bottles with a rotating chuck. Used by bottlers and cap suppliers to qualify seals and prevent leaks or tamper band failures.

Specification

The bottle is held in a rubber-lined clamp and the cap is turned by a motor while peak torque is displayed. Both tightening and opening torque are recorded in N-cm or in-lb. Results help set capping machine pressure and verify consistency across lines.

Features

• Torque range 0 to 5 N-m with peak hold
• Rubber-lined bottle clamp avoids slipping
• Motorised constant speed rotation
• Unit selection of N-cm, N-m and in-lb
• Adjustable cap chucks for 28 to 63 mm diameters
