Digital Cap Torque Tester CTT-series is designed to meet the testing requirements of bottling/capping processes in the pharmaceutical and food and beverage industries primarily.

It is designed to measure the torque force in Newton-meters (N-m) for bottle and containter, lids, caps and closures.  

The purpose of torque testing is to find the right torque, then check your production equipment is obtaining and repeating the correct result.  Settings can then be adjusted for higher or lower torque accordingly. 

The importance of such testing is illustrated by the example; If a consumer cannot open a soft drink bottle then they are unlikely to buy that soft drink.  The opposite also applies that you do not want a lid to be so loose that it is too easy to open accidentally and allow the product to spill or spoil; i.e. cosmetics, medicines and chemicals. Safety and freshness seals can also be applied and checked for integrity.

Widely adjustable grips mean the CTT-series can also be used in other rotational force applications such as measurement of zoom and focus mechanism of camera lenses and even other,  non circular containers as used for motor oils and the like.

Built with a solid, yet compact design the CTT-series comes with a USB cable for data output to computer.  There is also an optional 2.4G mini printer for instant data results on site.  Data can be displayed numerically or as a spectral torque curve graph. 



To use the cap torque tester you clamp the jar or bottle in the feet (grips) of the tester and as you apply force to remove the lid jar or bottle, the tester takes torque measurements.  Once the bottle or jar is opened the torque is no longer transmitted through the whole object and the measurements are complete.  The tester is able to take peak measurements being the highest amount of torque and is able to take tracking measurements showing the different levels of torque through the motion of opening the bottle or jar.
