Voltage detection range

The Wiha 25506 is a non-contact voltage tester that detects AC voltages from 12 to 1000 volts. It meets CAT IV safety standards and complies with IEC requirements. A red LED in the plastic tip illuminates and an audible warning sounds when voltage is present. The tool is hand-powered and includes a built-in flashlight for low-light work.

Indoor electrical work

Electricians and maintenance technicians can use this tester for quick, non-contact checks on live terminals. The universal measurement tip supports international outlet types. Buyers who need contact-based measurements or DC voltage detection should look at a different instrument. The device requires two AAA batteries, which are not supplied.

CAT IV 1000 V rating

The single specification that decides suitability is the CAT IV 1000 V rating, which certifies the tester for use at the service entrance and on outdoor conductors. If the job requires a lower category rating only, this tester still works but exceeds the requirement. Verify that the 12 V minimum threshold matches the lowest voltage you must detect.

Questions about this item

Does the Wiha 25506 need batteries to operate the voltage detection and flash light?

The tester ships without batteries; install two AAA alkaline cells to power the LED tip, audible alert and built-in flash light.

Can I use this 12-1000 V CAT IV detector on the same circuits as my older CAT III meter?

Yes, the CAT IV rating covers the same 12-1000 V AC range and adds higher transient protection for service-entrance panels.

How do I confirm the 25506 is detecting voltage correctly after installing the batteries?

Bring the tip near a known live conductor; the red LED in the plastic tip lights and the audible warning sounds when the field exceeds 12 V AC.
