All measuring equipment needs calibrating to ensure a precise, accurate result and the tools used in portable appliance and electrical testing are no exception. The IET PAT Testing Code of Practice states that you should have your equipment calibrated at least once every 12 months, though tools that are used extremely frequently may require more regular calibration. It's also advised that any damaged equipment be calibrated immediately after repairs.
We here at Testermans understand how important it is for you to receive a fast, professional service; every day your tools are being calibrated is a day they're not in use, which is why we are confident we can offer to have your equipment calibrated and ready to ship within as little as three days of receipt!
So if you need your tools calibrating, look no further than Testermans. Just follow the three easy steps below and we can get to work calibrating your equipment ASAP!
