Megger MIT1015 10 kV Insulation Resistance Tester
- MIT1015 from the ‘Essential Range‘
The Megger MIT1015 is a high-performance Essential range insulation resistance tester, designed to deliver accurate and dependable measurements up to 20 TΩ at 10 kV. Purpose-built for technicians, contractors, and maintenance engineers working with higher-voltage systems, the MIT1015 combines simplicity, safety, and ruggedness in a portable package.
As part of the Essential category, it offers all the core insulation resistance tests most professionals need, without extra complexity. You get the patented PI predictor for time savings, RE>Act mode for enhanced accuracy and safety, and Megger’s dual-case construction for maximum durability in harsh working conditions.
Why choose the Megger MIT1015?
If you regularly work on assets rated above 5 kV and want an insulation resistance tester that is simple to operate, dependable in the field, and safe to use in demanding electrical environments, the MIT1015 is a perfect fit.
It’s designed for “go/no-go” testing, commissioning, and routine maintenance, with excellent noise rejection (up to 3 mA) for stable readings in LV and MV networks.
Key features of the Megger MIT1015:
- RE>Act mode – detects and measures reabsorption current for more reliable IR values.
- Patented PI predictor (PIp) – predicts PI results mid-test, saving valuable time.
- Measures insulation resistance up to 20 TΩ at 10 kV.
- ±5% accuracy to 2 TΩ at 10 kV.
- 3 mA noise rejection for accurate readings in LV/MV environments up to 45 kV.
- Safety rated CAT IV 1000 V (up to 3000 m altitude).
- Operates from rapid-charge Li-ion battery or AC mains.
- Rugged dual-case design for enhanced protection.
- Large, backlit colour display for easy reading in all conditions.

❓ Frequently Asked Questions (FAQ)
Q1: Does the MIT1015 have data storage?
A. No – as an Essential range model, it is designed for direct, on-the-spot testing without recording results.
Q2: Can I use the MIT1015 in noisy electrical environments?
A. Yes – it has up to 3 mA of noise rejection, suitable for LV/MV systems. For HV/EHV work, an Advanced or Expert model is recommended.
Q3: Can I run the MIT1015 from AC mains?
A. Yes – it can operate from mains power when the battery is low, but charging stops during active testing.
Q4: Is the MIT1015 portable?
A. Yes – it’s lightweight and supplied with a protective carry case for field work.
Choosing the right tester
Pick the MIT1015 if you need the capability of a 10 kV insulation resistance tester but don’t require advanced diagnostics, data storage, or connectivity.
It’s best suited for:
- Utilities carrying out commissioning and post-repair testing of high-voltage assets.
- Industrial users with HV motors, transformers, and cables needing accurate “go/no-go” results.
- Field engineers who work in environments where rugged build quality and simplicity are more valuable than extra features.
If your testing requires trend analysis, data logging, or working in higher-noise HV environments, step up to an Advanced range model like the MIT1025. For extreme noise immunity and adaptive filtering in EHV conditions, the Expert range would be the right choice.
Category Comparison:
The MIT1015 sits in the Essential range, offering the higher 10 kV output compared to the MIT515’s 5 kV, while keeping the same straightforward, rugged design philosophy. It’s ideal for users who need high-voltage insulation resistance testing without the advanced diagnostics or connectivity found in the Advanced range models (such as the MIT1025 or MIT1525).
Compared to the Advanced range, the MIT1015 lacks:
- Onboard memory and data logging
- USB/Bluetooth® data transfer
- Selectable test currents and advanced diagnostics (PDC, Ramp, DD tests)
Its strength lies in being a reliable, accurate, no-frills high-voltage tester for commissioning, maintenance, and repair work where a simple “test-and-go” approach is preferred.
