How Does Digital Torque Wrench Work

You may come across many types of torque wrenches in the market and digital torque is one of them right now. 

The digital torque wrench is just a usual torque wrench only that it has a digital or electronic readout of the torque value. Because it is digital, it would make it possible for you to program the torque limit with ease. 

When it comes to using it, consider doing it like any other torque wrench you have used before. Well, it is equipped with an LED reading which gets its data from the torsion rod transducer. 

The digital torque wrench comes equipped with LED lights too. Their work is to notify the user when approaching the selected torque. Once the torque is achieved, an audible alert is sounded. 

Some models may have a computer chip that allows you to save the torque values. If you can save the content, you will have an easy time retrieving and analyzing the data depending on your needs.

Handle comfort
