Non-contact AC voltage tester

The MUFASHA tester detects alternating current from 12 V to 1000 V without touching conductors. Electricians and DIY users can safely verify live wires, sockets, switches and lights that have stopped working. A built-in flashlight and red pointing light help in dark or confined spaces. The pen-style body weighs 1.42 ounces for easy pocket carry.

Replaces contact probes and guesswork

Switching from contact testers removes the need to expose bare conductors, reducing shock risk during quick checks. The dual sensitivity modes let you choose high range for general 12 V–1000 V scanning or low range for 48 V–1000 V pinpointing in crowded junction boxes. The jump is worth it when you need audible and visual alerts that distinguish voltage levels instantly. Not for users who require DC measurement, continuity testing or exact numeric voltage readouts.

Simple one-button operation

Press and hold the power button to start, then short-press the H/L button to toggle sensitivity and the light button for illumination modes. Common issues include false alerts from induced voltage on ungrounded metal near AC lines and missed detection if the break point is shielded or the battery is low. Always confirm the wire carries AC current before relying on break-point indication.

Questions about this item

What size pocket or tool pouch fits the 1.42-ounce detector pen?

At 1.42 ounces the pen is light enough for a shirt pocket, a small tool-belt pouch or any compartment that holds a standard marker.

How do I switch between the 12 V–1000 V high mode and the 48 V–1000 V low mode, and what step do users often miss?

Press the H/L button once to toggle; the step people miss is verifying the mode letter on the display before testing.

When will the two AAA cells need replacing?

Replace the batteries when the flashlight dims or the beeper sounds weak, typically after several months of intermittent use.
