Description

Metrel MI3100-S Eurotest Easi Multifunction Tester

Product Details:

Only weighing 1.3kg, Metrel has created a portable lightweight Multifunction Tester with thoughts of you in mind. The kit includes hard-wearing rubber grips, and a soft carry case acceptable for all the testers accessories.

The Metrel MI 3100 S is the successor to Metrel’s MI 3100 Multifunction tester and offers more features, therefore, making it a more versatile instrument.

The Metrel MI 3100 S will benefit anyone constantly encountering troublesome RCDs. It has a testing mode ‘All 6 in 1 Visit’ for RCD testing and easily reset the breaker to allow the MI 3100 S to carry out all tests needed. You will remain protected on all test ranges to avoid damage often caused by incorrect connections across phases.

Key features:

  • Built-in help screens for referencing on site.
  • Built-in fuse tables for automatic evaluation of the line / loop impedance result.
  • On-line voltage monitoring: monitors all 3 voltages in real-time.
  • Polarity swap: automatic polarity reversal on continuity test.
  • Trip Lock function: loop impedance test without tripping the RCD.
  • Built-in charger unit has a built-in charging circuit and comes complete with a set of rechargeable NiMH batteries.
  • RCD auto: automated RCD testing procedure.

Measuring functions

  • Insulation resistance with DC voltage from 50 V to 1000 V;
  • Continuity of PE conductors with 200 mA test current with polarity change;
  • Continuity of PE conductors with 7 mA test current without RCD tripping;
  • Line impedance;
  • Loop impedance;
  • Loop impedance with Trip Lock RCD function;
  • TRMS voltage and frequency;
  • Phase sequence;
  • RCD testing (general and selective, type AC, A, F);
  • Earth resistance (3-wire method)

🚚 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.
📞 01945 738112 | ✉️ [email protected]


📦 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.


📝 Important Notes

  • Please ensure your delivery address and contact number are correct at checkout.
  • Undelivered parcels may be returned to us after a short holding period.
  • Redelivery or return fees may apply, even if your order originally qualified for free delivery.
  • By placing an order, you confirm your understanding and acceptance of this policy.
