Loop Tester Calibration

We calibrate loop testers used to verify earth fault loop impedance and help assess the safety and performance of electrical installations.

Loop testers are commonly used during installation, inspection, fault finding and verification work where dependable loop impedance measurement is essential.

Our calibration checks relevant operating points 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.
