Do digital torque wrenches need to be calibrated – complete guide

In order for a digital torque wrench to produce accurate readings, it must be properly calibrated. When a digital torque wrench is brand new, it will most likely come pre-calibrated from the factory.

However, over time and with extended use, the readings of a digital torque wrench can become less accurate. While some may argue that re-calibration is unnecessary, we believe that it is always wise to be safe than sorry when dealing with something as crucial as the precision of your torque wrench.

There are two main ways to calibrate a digital torque wrench: sending it out to a professional calibration company or doing it yourself. If you decide to send your digital torque wrench out to be professionally calibrated, make sure to do your research ahead of time and choose a reputable company.

The cost of professional calibration services can vary depending on factors such as the location of the company and the type of calibration being performed.

If you decide to calibrate your digital torque wrench yourself, many instructional videos and articles available online can walk you through the process step-by-step. Although this process may take some time, it will save you cost in the long run since you will not have to pay for professional calibration services.

Calibrating your digital torque wrench is a relatively simple process that can usually be done in-house. However, many companies offer calibration services if you don’t feel comfortable doing it yourself.

How often does a digital torque wrench need to be calibrated?

Many industries require the use of torque wrenches to ensure that fasteners are correctly tightened. As a result, torque wrenches must be calibrated to avoid over or under-tightening fasteners. But how often does a digital torque wrench need to be calibrated? Let’s take a look.

The frequency with which you need to calibrate your digital torque wrench will depend on several factors, including:

  • The type of torque wrench you have
  • How often is the wrench used
  • The level of accuracy required
  • The environment in which the wrench is used

For example, a torque wrench that is used daily in a controlled laboratory environment will need to be calibrated more frequently than one that is used infrequently in an industrial setting.

Most experts recommend that digital torque wrenches be calibrated at least once per year. However, some companies have internal calibration policies that call for more or less frequent calibration depending on the above factors.

If you’re unsure how often your digital torque wrench needs to be calibrated, check with your company’s quality control department or the manufacturer of the wrench.

How much does it cost to calibrate a digital torque wrench?

The calibration cost can vary widely depending on the size and brand of your digital torque wrench. Generally speaking, it is less expensive to calibrate a small, handheld wrench than to calibrate a larger, industrial-grade model. It can be approximately 20 to 200 dollars.

However, the frequency with which you need to calibrate your wrench will also play a role in the overall cost. It is best to contact a local calibration laboratory to get an accurate calibration cost for your specific wrench.

The calibration process usually involves attaching the torque wrench to a device known as a load cell and rotating it until it reaches the desired torque level. Once the desired torque level is reached, the load cell records the output so that it can be compared to the readings on the torque wrench itself.

If you find that there is a discrepancy between the readings on the load cell and the readings on your torque wrench, you’ll need to adjust the calibration settings on your wrench until they match. Once they match, your digital torque wrench is calibrated correctly and ready for use!

Besides calibration checks, are there other ways to keep it in good working order?

Digital torque wrenches are a valuable tool for those who need to apply precise torque to fasteners. They are used in various industries, from automotive manufacturing to aerospace assembly.

While calibration checks are the most crucial step in maintaining a digital torque wrench, there are a few other things that can be done to keep it in good working order.

  • First, it is essential to clean the sensor and surrounding area regularly. This will help prevent the build-up of dirt and debris, which can interfere with the wrench’s accuracy.
  • Second, the battery should be checked frequently and replaced as needed.
  • Third, it is a good idea to keep spare parts on hands, such as sensors and cables.

With these simple things in mind, you can be confident that your digital torque wrench will provide years of reliable service.

How can you tell whether or not a digital torque wrench is giving accurate readings?

A digital torque wrench is a valuable tool that ensures that you apply the right force when working with bolts and screws. However, it’s essential to ensure that your wrench gives accurate readings; otherwise, you could damage the materials you’re working with. There are a few signs that indicate something wrong with your digital torque wrench.:

  • The readings are consistently off by a small amount. This could be due to calibration issues and can usually be fixed by recalibrating the wrench.
  • The readings jump around or fluctuate excessively. This is usually caused by a loose battery connection and can be remedied by tightening the battery compartment.
  • The wrench shuts off randomly or gives inaccurate readings when used in certain temperature extremes. This could indicate a problem with the electronics, and you may need to have the wrench serviced or replaced.

If you witness any of these problems, it’s important to take action immediately; otherwise, you could end up causing severe damage to the materials.


So, do digital torque wrenches need to be calibrated? I hope you got the appropriate answer from the above articles. While torque wrenches are vital tools, they require some care and maintenance to work properly. This includes regular calibration to ensure an accurate reading every time. With proper care and periodic calibration, your digital torque wrench will provide years of reliable service!

If you have any queries about whether or not your digital torque wrench needs to be calibrated, don’t hesitate to ask a professional.
