Calibration Checkboxes

About Calibration Checkboxes

Compatible with PAT testers, multifunction testers, insulation testers, continuity testers and more, calibration checkboxes are must-have accessories that ensure you can check the overall accuracy of your tester in the time period between official calibration by a certified laboratory.

Calibration checkboxes vary both in size and ability; smaller boxes generally have smaller ranges, while larger boxes may come housed in their own protective carrying case and carry out more comprehensive measurements.

We recommend using a calibration checkbox regularly with your tester to ensure that your results haven't been affected by drift. Several factors ranging from direct drops of the tester to overcurrent passing through circuitry can cause inaccurate readings, so using a checkbox ensures that your meter remains correctly calibrated and is generating the results you need.

If you have any questions about our range of calibration checkboxes, please give us a call and we'll be happy to help you.
