If you frequently use a torque wrench, then you must have a digital torque wrench tester CEM20N3X10D to adjust and calibrate a wrench that is loaded manually. The wrench is secured by the pole holder so that it is positioned optimally for testing. It has a memory for storing many measurement data items. The display screen shows minimum value, maximum value, quantity, and mean value. This digital torque wrench tester CEM20N3X10D must also be tested periodically for accuracy by using a separate calibration kit.
