Description

Megger MIT1525 15kV Insulation Resistance Tester

Product Details:

The Megger MIT1525 is a high-performance insulation resistance tester designed for professional use, completing Megger’s range of high-voltage MIT testers. With an output of up to 15kV DC and the capability to measure insulation resistance values as high as 30TΩ, the MIT1525 is the ideal tool for advanced insulation testing across a variety of industrial applications.

Comprehensive Testing Capabilities

The MIT1525 offers a versatile array of testing modes to suit any insulation diagnostic requirement, including:

  • Timed Insulation Resistance Testing
  • Polarisation Index (PI)
  • Dielectric Absorption Ratio (DAR)
  • Step Voltage Testing
  • Dielectric Discharge (DD)
  • Ramp Testing

Step voltage testing is particularly useful to assess the insulation and cables’ ability to withstand day-to-day voltage spikes, such as those generated by motors in operation. The MIT1525 allows fine-tuned step-voltage adjustments: 25V increments between 1kV and 5kV, and 50V increments between 5kV and 15kV.

Enhanced Data Management

The MIT1525 features an advanced internal memory system with time and date stamping, allowing users to store up to 5.5 hours of measurements taken at 5-second intervals. Data can be reviewed directly on the large backlit screen or exported to a PC using the included Megger PowerDB Lite software via USB for live-time analysis and reporting.

Designed for Ease of Use and Durability

With its dual rotary switches, the MIT1525 is intuitive to operate, even in demanding environments. The large, backlit display simultaneously shows critical testing parameters such as:

  • Resistance
  • Voltage
  • Leakage Current
  • Capacitance
  • Battery Level
  • Test Time

The rugged dual-case design provides excellent protection from impacts and is fire retardant, ensuring long-lasting reliability. When closed, the lid creates a secure seal offering IP65-rated moisture and dust resistance, making the MIT1525 suitable for use in harsh environments.

Power Options and Calibration

The instrument operates on a rechargeable Li-ion battery or AC mains supply, offering flexibility for field and workshop use. Each MIT1525 comes with a calibration certificate as standard, ensuring precise and reliable measurements.


Why Insulation Resistance Testing Matters

Insulation can degrade over time due to factors such as temperature, current flow, physical wear, chemical exposure, and environmental conditions. Regular insulation resistance testing is crucial for maintaining both the safety and reliability of electrical installations, helping prevent costly failures or hazards in service.

🚚 Testersmans Shipping Policy

Free Mainland GB Delivery Over £150

We offer free delivery on most mainland Great Britain orders over £150 (ex VAT).
This applies across England, Wales, and most of Scotland, excluding certain remote or offshore postcodes.

If your order total falls just short of £150, or you’re a returning customer, feel free to contact us — we may be able to offer a discount code or delivery workaround.

📦 UK Delivery Options

We work with both Royal Mail and DHL to offer reliable and flexible delivery across the UK:

  • Royal Mail – Best suited for lighter parcels and for customers in remote regions, including the Highlands, Islands, and Northern Ireland.
  • DHL – Ideal for most mainland UK orders, providing fast, tracked delivery and excellent reliability for time-sensitive shipments.

Our checkout system automatically displays the available delivery services for your postcode and order weight, ensuring you always see the most suitable options.

Note: Heavy, bulky, or freight-only orders will be charged separately.
Our website is designed for quick, transactional purchases rather than bulk or palletised orders.
Please contact us in advance for a tailored freight quotation if your order falls into this category.


⏱ Dispatch & Delivery Timing

We aim to dispatch all in-stock orders promptly, but delivery depends on both when you order and which service you select.

  • UK orders: placed by 2:00 PM Monday–Friday are usually dispatched the same day.
  • International orders: placed by 2:00 PM Monday–Thursday are usually dispatched the same day.

Orders placed after these times are processed the next working day. This means delivery may occur the following day or later, depending on the courier and service selected.

Once dispatched, your chosen delivery service determines how quickly your parcel arrives:

  • Standard services We use Royal Mail Tracked 24 or DHL Parcel as our ‘Standard’ services. They are not guaranteed to arrive next working day.
  • Premium services (e.g. Royal Mail Special Delivery or DHL by Noon) offer guaranteed delivery windows.

If your order is time-sensitive, we strongly recommend choosing a guaranteed service or contacting us before ordering to confirm availability.

Please note: For logistical reasons, we may occasionally adjust the delivery method selected at checkout. For example, smaller items may be better suited to letterbox-friendly packaging or may be at greater risk of delay or loss via certain services. We actively monitor courier and postal service disruptions—including strikes and delays—and may modify shipping arrangements to help ensure timely and secure delivery.


📅 Busy Periods & Delays

We always aim to dispatch promptly, but delivery times may be affected by:

  • Seasonal demand (e.g. Christmas, bank holidays, or industry shutdowns)
  • Courier network delays outside our control
  • Supplier lead times or calibration requirements for certain equipment

If your delivery is time-critical, please contact us before ordering so we can confirm stock and courier availability.


🌍 International Shipping

We ship worldwide using UPS Express Saver® and other trusted global courier partners. All international shipments are tracked and generally dispatched Monday to Thursday to ensure smooth customs clearance and transit.

Estimated delivery times:

  • Europe: 1–2 working days
  • North America: 2–3 working days
  • Asia-Pacific & Rest of World: 3–5 working days

Delivery times vary depending on location, customs clearance, and local courier performance.


💰 Taxes, Customs & Import Duties

International customers are responsible for any applicable taxes, customs charges, or import duties.
These are not included in our product or shipping prices.

Your courier will typically provide a secure payment link for any import charges once your parcel reaches customs.
If import fees are refused and the parcel is returned, we will issue a refund minus all incurred shipping and return costs.


📍 Using Your Own Courier

If you would prefer to arrange collection via your own courier (UK or international), please contact us before placing your order to coordinate collection from our Wisbech warehouse.
