All tools and devices that are torque controlled are tested and calibrated using a torque tester. The quality control device finds use in metal, medical, aerospace, and many other industrial sectors to measure several properties, from torsional strength to stiffness. This torque tester CD 100M has a digital display that displays the resultant torque value on the screen. This value is evaluated by the testing machine by calculating the output signal reading from the transducer into a torque value.
