Description
Martindale VI-13800 Fuseless Voltage Indicator
Product Details:
- The VI13800 is an essential tool for proving electrical circuits are dead before carrying out maintenance and installation work in accordance with safe isolation procedures. The VI13800 ensures safety through simplicity, with no ranges, switches or batteries, reducing the risk of an incorrect reading.
- The VI13800 provides instant visual AC and DC voltage indication in four stages from 50V to 400V. The bright long life LED indicators give clear and immediate display of the voltage level range.
- It has retractable probes, heavy duty finger guards and a two layer double insulated cable with a white inner core to give clear indication of damage that might compromise the user’s safety.
- The latest design complies with the new standard relating to 2 pole voltage indicator, BS EN61243-3 and the requirements of GS38 Edition 4 2015.
- The latest version of BS EN61243-3:2010 came fully into force in May 2013 and all voltage indicators on the British & European market should comply. The VI13800 replaces the industry standard VI13700.
- Based on the VI13700, the new design includes a high wattage resistor instead of a fuse that will limit the current in the event of damage to the cable in accordance with BS EN61243-3.
- The protection is built in where it’s needed, in the handheld probe assembly rather than just in the instrument providing superior protection for the user to other testers. The probes tips have retractable covers which can be locked in place and can’t get lost.
- The Martindale VI13700 has been widely used for many years and as part of its design has always included a fuse in the probe to limit the current in the event of damage to the cable.
- Apart from the fuse/resistor enhancement in the probe everything else about the specification of the VI13800 is identical to the VI13700/2, including the contrasting inner cable sheath to quickly identify cable damage.
- In order to distinguish VI13700/2 from VI13800 the new model has the probe changed to all black instead of yellow.
- The probe is clearly marked “impedance protected” rather than showing a fuse rating. It is sealed and has no user replaceable parts.
- There is no specific requirement to replace the VI13700 products which are in use. NB Proper proving procedures should always be used with any voltage indicator.
- The new VI13800 is available to purchase on its own or as part of a kit, the VIPD138LOK, containing everything you need for on-site working. Kits includes a Martindale proving unit, combination carry case and locking off devices, enabling full compliance with health and safety recommendations for safe working which require voltage indicators to be proved before and after use and the point of isolation to be locked off with a caution notice.

- 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.
