Torque Testing Instrument

Torque testers measure the torsional strength of materials by applying rotational force, and are widely used in packaging and hardware industries to test the torque required to break screws, bottle caps, and other products, as well as their rotational sealing performance.
Selection
When selecting, consider the type of test material and torque range, match the fixture size, confirm the rotational speed control accuracy, check the data acquisition method, and evaluate the equipment size and spatial compatibility.

Practical Guide to Selecting Rotors and Speeds for Rotational Viscometers
A rotational viscometer measures viscosity by detecting the resistance encountered by a rotor rotating in the sample. When selecting a rotor, it is necessary to consider the estimated viscosity range of the sample, ensuring that the torque reading falls within 10% to 90% of the instrument's measurement range, while also taking into account the sample volume and rheological properties.
