Insulation Tester (Megger) Calibration in Bangladesh
ION Engineering calibrates insulation resistance testers (meggers) across their test voltage and resistance ranges against traceable electrical references, accredited to ISO/IEC 17025:2017.
What We Calibrate
Handheld Insulation Testers
Battery-powered megger testers used in field electrical work.
Motorised / High-Voltage Testers
Higher-voltage insulation testers used for larger equipment.
Multi-Function Testers
Combined insulation and continuity test instruments.
How We Calibrate an Insulation Tester
The instrument’s test voltages and resistance ranges are checked against traceable electrical reference standards at multiple points, with as-found and as-left readings recorded — confirming both the applied test voltage and the resistance reading are accurate, since an insulation tester’s own error can mask a real cable fault.
What’s included
- Test voltage and resistance range verification
- As-found and as-left readings, per point
- Stated measurement uncertainty
- QR-verifiable certificate
Insulation Tester (Megger) Calibration FAQs
How often should an insulation tester be calibrated?
Annually is standard for testers used in routine electrical safety work, calibrated alongside your other electrical safety testing instruments.
Do you calibrate high-voltage insulation testers?
Yes, motorised and higher-voltage testers are calibrated at their rated test voltages using appropriate reference standards.
What measurement uncertainty do you report?
Uncertainty is stated per range on your certificate; our full accredited scope is published on our calibration capabilities page.
Is the certificate independently verifiable?
Yes, every certificate number can be checked using our online verification tool, with no login required.
