Keep yourself safe and work with professional precision. The VoltPenni features advanced NCV sensing technology to detect live wires through walls and conduits without direct contact. The essential smart tool for every homeowner and professional electrician.










Unseen currents are the biggest danger in any home project. VoltPenni uses Non-Contact Voltage (NCV) induction to alert you to live wires from 20V to 1000V before you even touch them, preventing dangerous shocks and accidents.
Electrical work often happens in dark corners or fuse boxes. VoltPenni integrates a powerful white LED torch and a bright LCD screen, so you can clearly see what you are testing and read measurements accurately in any environment.


Standard testers are often unreliable. VoltPenni offers smart digital contact testing from 0-300V with a 50/60Hz frequency range, giving you the professional-grade data required for safe repairs and installations.



"The VoltPenni is an essential addition to any toolbox. Its ability to switch between non-contact NCV sensing for safety and direct contact for precise voltage measurement makes it far superior to traditional single-mode testers."
– Robert Sterling, Professional Master Electrician

Frequently Asked Questions






I do a lot of DIY home renovations. The VoltPenni has saved me from several potentially dangerous shocks by detecting wires I didn't know were live. The torch is also surprisingly bright and helpful!

As a professional electrician, I need tools I can rely on. This tester is as accurate as my expensive industry gear, but much more convenient to carry in my pocket. The LCD screen is crystal clear.

The non-contact detection is very sensitive and reliable. I use it every time I change a light fixture or outlet. It gives me peace of mind knowing the power is truly off before I touch anything.
