NWS N819-4 Voltage Tester Clip Attachment

The NWS System Clip Voltage Tester N819-4 is an innovative contactless voltage tester designed to integrate seamlessly with compatible NWS SoftGripp® ergonomic hand tools, giving professional electricians a convenient method of checking for the presence of AC voltage without carrying a separate tester.

Compact, lightweight and easy to attach, this clever accessory clips securely onto compatible NWS pliers and cutters, ensuring it's always within reach when working on electrical installations, maintenance or fault-finding tasks.

Combining non-contact voltage detection with an integrated LED torch, the N819-4 improves efficiency while helping electricians work more safely and confidently in domestic, commercial and industrial environments.

Designed to detect alternating current (AC) voltages from 90V to 1000V, the N819-4 uses a contactless voltage field sensor to identify live electrical circuits without requiring direct metal-to-metal contact.

This makes it ideal for quickly checking cable connections, mains sockets, junction boxes, circuit breakers, fuses and other electrical components before work begins. A bright red LED visual indicator immediately alerts the user when voltage is detected, while the simple push-button operation incorporates a built-in self-test and a white readiness indicator to confirm the tester is functioning correctly before every use.

For added practicality, the tester features an integrated LED torch that illuminates measuring points when working in lofts, ceiling voids, consumer units or other poorly lit areas.

The lightweight plastic housing is durable enough for everyday professional use, while an integrated eyelet allows the tester to be secured to a lanyard for added convenience when working at height.

Manufactured in Germany to the high standards associated with NWS professional hand tools, the N819-4 complies with EN 61010-1 and is rated to Measurement Category CAT III 300V, providing reassurance for electricians carrying out routine testing and installation work.

It offers a dependable, practical solution for professionals looking to enhance both safety and productivity. Whether used for identifying live circuits, performing preliminary safety checks or illuminating confined work areas, the NWS System Clip Voltage Tester is a compact yet invaluable addition to any electrician's toolkit.
