To make sure torque wrenches provide reliable and precise measurements, they should be regularly calibrated.
This is the procedure of checking the accuracy of a measuring instrument – as well as the adjustment to align it with the standard. The process allows equipment to produce more accurate results than would’ve otherwise been possible.
It’s vital to regularly calibrate instruments, as their accuracy will reduce over time and with use. The permitted frame of calibration error is 5% – with any error beyond that potentially affecting the performance of the tool quite seriously, which could lead to liability for product failure.
We offer calibration for new and existing equipment, with specialists in our laboratory offering RS and UKAS-accredited services – which is recognised internationally as the industry mark of quality.

How are they calibrated?
It’s recommended that all test and measure instruments are taken to accredited laboratories to be professionally calibrated.
Testing the tools highlights any potential problems and allows them to be fixed before they can lead to a serious issue. Calibration also ensures the user can have confidence in the accuracy of their tool and that it complies with international standards.
How often should they be calibrated?
How often this needs to be done depends largely on how frequently the tool is used, as there aren’t strict or legal time periods for having it calibrated.
It’s thought by some professionals that the performance is affected between 2,500-3,000 repetitions, so it’s recommended to have it calibrated once it reaches 2,500 repetitions.
If the tool isn’t frequently used, then around once a year is the recommended timeframe for calibration to guarantee accurate measurements.
