Non-Contact Voltage Tester Pen

This two-pack provides non-contact AC voltage detection from 12 to 1000 volts. It suits electricians, DIY enthusiasts and homeowners needing a portable tool to identify live wires, outlets or static electricity without direct contact. A built-in LED flashlight adds illumination for dark work areas. The pens comply with CE CAT III 600V and RoHS standards.

Buyers wanting dual-range sensitivity

The "S" button switches between high sensitivity at 12-1000V AC and low sensitivity at 48-1000V AC to reduce false alarms near strong fields. Distinct buzzer frequencies and LED colours help distinguish live from neutral conductors. It is not for users who require DC voltage measurement, continuity testing, current clamping or a digital numerical display of exact voltage values.

Sustained detection behaviour

Under continuous proximity to an energised conductor the pen maintains its audible and visual alarms without timing out. The 40-gram body stays cool during extended use because it draws only minimal battery current. AAA cells power the unit; the manual advises verifying function on a known live source before each session to ensure reliable operation.

Questions about this item

Does the tester need batteries to operate, and which size?

It is battery powered and the pack includes four AAA cells so you can start testing immediately.

Will the 12 V low-voltage range pick up signal from a standard 12 V automotive circuit?

Yes, the high-sensitivity mode covers 12 V to 1000 V AC, so a 12 V vehicle circuit falls within its detection span.

How can I confirm the tester is functioning correctly before I rely on it?

Test it on a known live conductor first; the tip should flash red and sound an alarm if the unit is working properly.
