NCV Voltage Tester Pen — Non-Contact Live Wire Detector

Three Warnings Before You Touch

Three colors tell you the voltage level

Red for high, yellow for medium, green for low gives an instant glance verdict no neon tester offers. Even in a dark panel, the glowing LED window is unmistakable.

Non-contact NCV with triple alarm

Light, color and sound fire together — a rapid beep and flashing red grab your attention even in noisy job sites or sun glare. You don't need to look directly at the indicator to know there's danger.

A flashlight that's always there

Built-in LED lights the junction box, crawlspace or attic so you test and see with one hand and one tool. No fumbling for a separate light while your other hand holds the pen.

Tune out the false alarms

Three sensitivity buttons let you dial detection up for deep wiring or down to avoid ghost voltage. One press cycles through sensitivity modes so the pen works in dense panels without random triggering.

Detect Voltage In Two Seconds

1. 1
   Power on and set sensitivity

   Press any button to wake the pen. Tap the sensitivity button to cycle through low, medium or high — start high for general detection, then dial down if you get false signals.

2. 2
   Sweep the probe near the target

   Hold the probe tip close to the wire, outlet or cable. You don't need to touch metal — the NCV sensor detects the electric field through insulation.

3. 3
   Read the color and listen

   Red glow and rapid beeping means high voltage; yellow and moderate beeping medium; green and slow beeping low. No light and no sound means it's safe to proceed.

From risky assumptions to safe checks

1. 1
   The wire you thought was dead

   You're inches away, screwdriver in hand, and a faint voice says 'it should be off.' That hesitation is your body knowing what your tools haven't confirmed.

2. 2
   Guessing is not a safety plan

   A neon screwdriver needs direct metal contact and gives one dim glow. A multimeter ties up both hands with leads. Neither answers the first question — is it live? — with the glance-and-go speed you need.

3. 3
   A warning before contact

   This pen speaks first. Wave it near a wire and the clear probe tip glows, the alarm sounds, and the LED panel lights the color that matches the voltage. No guesswork, no contact.

4. 4
   Three jobs, one pocket

   Voltage detector, break tracer, and flashlight live in a single matte black body. One tool that replaces three, so every bag carries a full safety check.
