KT5 Open Jaw Current And Voltage Tester

  • A multifaceted instrument, the KT5 is capable of simple voltage detection and current measurements. Its capacity for non-contact voltage tests with 3 varying levels of sensitivity, locating hidden cables not to mention the 2 pole and single pole testing capabilities, (with either probe) makes this device a capable companion for electricians.
  • If you are looking for digital multi-meter functionality the Kewtech KT5 Open Jaw And Voltage Tester offers frequency, diode and phase rotation testing built in, a handy measurement hold function and continuity test faculty. This flexible instrument also boasts multiple voltage detection indicators such as LEDs, buzzers, and vibration
  • Kewtech have equipped the KT5 with permanent GS38 probe tips, reducing the possibility of losing the tips or impeding reach into typical sockets or devices like RCBO’s. The probe tip cover in the KT5’s nose is used to depress the earth pin in traditional UK BS1363 sockets. This small but perfectly formed machine also comes with LCD display and optional back light, a torch for use in poorly light environments, IP54 and CAT IV to 600v rating and even has probe storage located in the Kewtech KT5s body itself.

Kewtech Kewprove 3 Proving Unit

With an output of 690V AC/DC and two contact points for AC and DC voltage, this unit allows you to verify your voltage testers and detectors wherever you are. The instant ramp up and then step down of the Kewprove 3 will prove several voltage levels and the high output proves all types of voltage detectors.
  • Please note the Kewprove 3 must be used by a qualified person in accordance with the manufacturer’s instructions due the hazardous voltage omitted by the unit.
  • Kewtech Kewlok Lockout Device

As a is a combination lock, the Kewlok allows the user to set to a memorable code of their own choosing and the design fits all toggle switch MCBs, RCDs, RCBOs and mains switches.

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

⏱ 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.
