Polarity Tester

When it comes to managing low voltage networks, reducing downtime is a top priority. That's why a polarity tester like the VisNet® Polarity Test Pen™ can make all the difference.

Not only is this polarity tester more accurate than other standard conductor testers, but it also boasts a self-testing function that ensures both correct function and operator safety. By quickly pinpointing the cause of the problem, electricians can reduce downtime and minimise the disruption to power systems. With the right polarity testing tools, fault-finding becomes faster and more efficient, allowing for more effective maintenance and repairs of low voltage networks.

VisNet Polarity Test Pen™

Engineered specifically for electrical engineers, our market-leading polarity testing kit provides complete certainty when identifying live conductors – even in tight spaces with bundles of cables.

The VisNet® Polarity Test Pen™ is exceptionally precise and will only alert you when within 3mm of a live core. No current flow in the live conductor is necessary; the Test Pen Checker™ simulates the electrical field created by a live conductor, allowing for accurate discrimination between live and non-live conductors. What’s more, the Polarity Pen is self-powered and portable, making it easy to use wherever you need it.

With this tool in your arsenal, you can quickly and confidently diagnose faults, minimise disruptions, and keep your low voltage network running smoothly.
