A test instrument is only trusted if its own accuracy is provable — which is why this category covers not just testers, but the calibration resistors, leads, and cases that keep them in a defensible, audit-ready state. This range is, in practice, the Megger catalogue gathered in one place around a single purpose: electrical inspection and testing work rather than general electrical maintenance. For the wider Megger product story, see the Megger brand page.
What's In Here
- Insulation & earth testers — the instruments doing the actual measurement, including digital and battery-powered units.
- Calibration resistors & reference standards — fixed-value resistors used to verify a tester's own accuracy before it's relied on for a certified result.
- Test leads, clamps & accessories — screened high-voltage leads, current and voltage clamps, sized to match specific instrument models.
- Carrying cases — instrument-specific protective cases, sold separately from the tester itself.
- Specialty instruments — digital tachometers and similar niche test equipment that ends up filed here rather than under a more specific heading.
Accessories in this range are usually model-specific rather than universal — a case or lead set built for one tester generation often won't fit the next, even from the same manufacturer. If you're replacing an accessory rather than the instrument itself, the tester's exact model number is what we need first.
Building an Audit-Ready Test Kit
An inspection report is only as defensible as the calibration record behind the instrument that produced it. We can supply testers with UKAS-accredited calibration certificates, and calibration resistors to verify accuracy between formal calibration cycles.
We are not affiliated with, or an authorised distributor of, the brand named on this page — genuine stock only, sourced and supplied independently. Orders ship worldwide with export documentation as standard; electrical contractors and inspection bodies across South Asia, the Gulf, and Africa are regular customers for this range alongside the UK.
