Description

Megger DLRO10X Digital Low Resistance Ohmmeter

Product Details:

The upgraded version of Megger’s DLRO10, this tester is capable of everything the other tester could do and also includes a number of unique new features.

Easily the most useful upgrade is the addition of built-in memory to the tester. This enables users to automatically store test readings and recall them at a later date either on the tester or on a PC, ensuring that extensive analysis can be carried out on one testing point over time or comparisons can be made between different conductor measurements. The DLRO10X also includes an alpha-numeric keypad to allow the user to manually adjust records and the memory of the tester can be sent to a printer to print out testing records.

When testing, the DLRO10 uses a four terminal resistance method to negate the resistance of test leads, thus ensuring measurement accuracy. Multiple test modes are available on the device, including normal testing, auto testing (which applied forward and reverse current), continuous testing for repeated measurements and a special inductive mode for use on inductive devices such as motors etc. The DLRO10X also comes with a unique unidirectional mode which applies current in a single direction (this is designed to speed up the overall measurement process).

The Megger DLRO10 can use multiple ranges when testing. The following table outlines the specific testing procedures possible and relevant data when testing with this low resistance ohmmeter:

This tester also comes with a few additional features including a full LCD display of test results, automatic test procedures to make life easier and the ability to check for noise on circuits and limit testing if excessive noise is detected.

📦 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.
