Insulation Tester Calibration

We calibrate insulation testers used to verify insulation resistance and help assess the condition and safety of electrical installations, equipment and circuits.

Insulation testers are commonly used during installation, maintenance, fault finding and certification work where dependable high-resistance measurement is essential.

Our calibration checks relevant test voltages and measurement performance to help ensure accurate, repeatable and consistent results.

No booking required — just walk in. Many calibrations can be completed While-You-Wait, depending on workload, tester condition and specification.

Alternative options include our 24/7 drop-off safe boxes, By Post service, or Extended Hours & Priority Booking.
