Keep your PAT verification kit accurate with our PAT Checkbox Calibration service. We test every range on your checkbox and verify readings against traceable standards. You get results you can trust, so your PAT tester checks stay reliable between full calibrations.
Manufacturers advise recalibrating a PAT checkbox every 12 months. That interval protects accuracy and extends service life. We also help you follow best practice from the IET Code of Practice. It recommends regular in-service checks between annual calibrations. Your checkbox makes that quick and simple.
Our technicians complete a thorough inspection, clean contacts and confirm all resistance and insulation points. We adjust where the hardware allows, then confirm stability. You receive a calibration certificate with measurement data and pass labels. We also store results, so re-orders stay effortless.
Compatibility matters. We calibrate checkboxes that support Seaward, Megger, Fluke, Kewtech, Metrel, Martindale, Socket & See and more. Your unit can verify different PAT testers, so one tool covers most fleets.
