Product Details:

Metrel MD9250 Industrial TRMS AC/DC Clamp Meter

The Metrel MD9250 Industrial TRMS AC/DC Clamp Meter is a versatile instrument with a number of impressive features. The MD9250 is the first clamp meter that meets overvoltage category CAT IV 1000 V, meaning users can operate with the peace of mind that this protection offers. Additionally, convenience and usability are at the centre of this unit’s design, with it being small enough for continuous single-handed operation. The large jaw opening allows for measurement of conductors up to 55mm in size, making its one-handed design philosophy even more impressive.

High resolution and accuracy in measurement, combined with the 2-line backlit LCD display (3-5/6 digits – 6,000 counts + 1,999 counts), provide the user with the precision and clarity required when working in the field. Moreover, the PC connectivity allowing users to transfer data from the unit to an external device, means further evaluation and long-term storage are an option. The 5ms Crest-Max mode enables this meter to capture in-rush currents, while the auto-ranging feature provides additional convenience in operation.

Measuring functions including TRMS AC/DC current and voltage, capacitance, temperature and full-range resistance make this the ideal tool for professionals within a range of industrial fields. Potential applications for this meter include solar power systems, UPS systems, utility scale battery systems and high level industrial electrical systems. This instrument is well-suited to potentially challenging environments, with it’s range-topping array of modes and features and single-handed design, Metrel offers a well-rounded and usable tool in the MD9250.

Key Features:

  • CAT IV / 1000V over voltage protection
  • True-RMS (TRMS) instrument: accurate measurements on sinusoidal & non-sinusoidal signals
  • VFD feature means you can measure true values in accordance with frequency
  • 2000A DC & AC clamp on measurement
  • AutoCheck mode provides low (ramp-up) input impedance to drain ghost voltages
  • Users can switch between automatic and manual ranging through the auto-ranging feature
  • Safety from lightning strike or switching surge (up to 12kV) through integrated transient protection
  • PC link: test results and data can be transferred to computer through optional software, allowing long-term storage or analysis
  • Hold function allows for temporary freezing of screen values for later viewing
  • Dual LCD display (3-5/6 digits – 6,000 counts + 1,999 counts) with powerful backlight for poorly lit conditions
  • Large jaws can measure conductors up to 55mm in diameter
  • 5ms Crest-max mode to capture in-rush currents
  • Temperature measurement up to 1000°C
  • Relative zero mode for comparing difference in signals or removing background noise

📦 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
