Digital Voltage Tester Pen 12-400 V Range Non-Direct-Contact Voltage Tester Pen Electrical Tool Built-in Display Handheld

This handheld digital voltage tester pen has a slim rectangular green plastic body with a metal point tip, built as a compact electrical tool for everyday circuit checks. Designed as an AC voltage tester, it works in the 12-400 V range and helps identify live wires, measure voltage, and check circuits with a simple front-button operation. As a non-direct-contact voltage tester, it supports quick sensing measurement, allowing you to detect electrical presence without direct point contact in many routine situations. The built-in display gives clear readings while audible and visual alarm functions add another layer of feedback, making the digital voltage tester pen easier to monitor during use. This voltage tester is suited for finding circuit breaks and confirming live conditions before work, helping support faster troubleshooting and more confident electrical checks.
