Spray bottle and other unique bottle/cap combinations can make torque verification and analysis a challenging proposition for this industry, but Mesa’s universal tooling approach offers solutions for these unique situations. Our Torque testers built to withstand corrosive chemicals which may come in contact with the tester. Mesa’s testers are also capable and built to handle oversized, and uniquely shaped bottles, which are prevalent in the chemical industry.
Release Torque Testing
Description: With a highly sensitive strain gage-based torque transducer, a 2000 CPR rotary encoder and proprietary pressure controlled cap and bottle gripper designs, our servo-driven automated torque tester can accurately detect both small and large changes in the torque and angle during the removal of a closure.
TEB (Tamper Evident Band)
Description: When tamper evident caps are used just knowing the release torque is not always enough, often knowing the torque required to break the bands is desired. Using a rotation driven release both the thread break and the band break can be measured. (See pg. 45 of ST-120S operator manual for info on how to set this up).
Description: With the ability to deliver and measure up to 88 lbf.in (10 Nm) of torque, we can find and report the torque it takes to strip out the threads when tightening your containers closure.
Description: Used to tighten a cap to a precise torque. Not often used by itself, aside from an evaluation or validation of a capping process, it can also be combined with the release testing for nondestructive testing as well as fatigue and accelerated aging testing.

ST-120S Industrial Cap Torque Tester
The ST-120S features a servo drive control, infinite chuck rotation, quick-change tooling, a color touchscreen interface, and faster cycle times. It boasts a corrosion resistant stainless-steel head enclosure and anodized aluminum frame construction. The unit is equipped with anti-bridging, anti-tie down anti-repeat dual actuation safety start switches, but for maximum operator safety, the ST-120S can be also equipped with a full machine guard.
Torqo 1600 Non-Destructive Cap Torque Tester
The Torqo 1600 is a durable and reliable computerized cap torque analyzer which is setting a new standard for torque measurement. With on-board microprocessors, it makes torque testing simple, accurate and affordable. The Torqo 1600 is easy to use, easy to set up, easy to move and low maintenance! Tooling is available for any threaded closure – including child resistant caps – and this compact unit delivers and stores precise results at the touch of a button.
Same as ST-120S, but the NEMA construction improves corrosion resistance and environmental rating (IP ingress protection). It is the recommended option in corrosive and wet environments (most beverage packaging lines are “washed down” on a regular basis, or spills occur. A higher NEMA or IP rating is better in those environments to ensure reliable operation. You could couple this with ergonomics, and the safety of both operator and machine.
