Check for live voltage without touching the wire. That means faster checks, less guesswork, and more confidence when you work around electrical systems.

See voltage status clearly through bright LED alerts and hear it instantly with the built-in buzzer. In quiet spaces, the UT12E model adds vibration feedback for a discreet signal.

Safer voltage checks with clear alerts

✅ Detects live circuits without direct contact for safer everyday testing

✅ Bright LED indicators make voltage status easy to read at a glance

✅ Built-in buzzer gives an audible alert when voltage is present

✅ 24–1000V detection range covers household outlets and industrial panels

✅ Auto power-off helps preserve battery life between jobs

✅ Magnetic field sensing mode on the UT12M supports quicker troubleshooting

✅ Vibration feedback on the UT12E gives a quiet alert in noisy or sensitive spaces

Waving the tip near wiring quickly shows whether voltage is present, so you can assess outlets, switches, cables, and junction boxes without direct contact. High and low sensitivity modes give you flexibility across different electrical systems.

The pen-style shape fits naturally in your hand and slides easily into a pocket or tool bag, so it stays close during service calls, repairs, and routine checks. It is built for daily field use, with a design that suits electricians, technicians, and DIY users who want fast confirmation before they proceed.

Bright LEDs, audible alerts, and the UT12E vibration mode make the result easy to understand in dim rooms, busy job sites, or loud environments. The UT12M magnetic field mode adds another way to identify energized components when you need more precise troubleshooting.

Work with greater confidence using a non-contact voltage tester that gives you clear, instant feedback.
