Improve the repeatability of your torque measurements.

Leak testing of bottles or flasks is traditionally done with a tabletop torque meter.

Issues of repeatability of measurements may arise, particulary between different users of the equipment.

Indeed, measurement bias can occur between individuals. This is what is commonly known as the human effect.

The two main bias factors are:

-The ovalization of the cap by the action of the user’s hand, when the thread is integral with the outside of the cap.

-The pressure exerted by the user on the cap when unscrewing, which increases the friction on the thread.

The speed of unscrewing is often mentioned, yet it has less influence on unscrewing measurements.

This unscrewing tool is suitable for grooved or non-circular caps.

Due to its shape and design, it considerably reduces ovality and greatly reduces the human tendency to press on the cap.
