Fast and secure detection using Wiha

Practical benefits

Safe non contact testing: You quickly detect alternating voltages from 90 to 1000V AC without establishing direct contact with live conductors.
Clear visual LED feedback: The steady green LED indicates operational readiness, switching immediately to a bright red light when voltage is present.
Globally compatible tip design: The internationally adapted measuring tip allows you to test all standard socket types worldwide with complete ease.

In a nutshell

The right choise for

With the Wiha SB25514 non-contact volt detector, you quickly and safely verify that your working environment is free of live voltage. You detect alternating voltages from 90 to 1000V ac without making direct contact with live conductors, eliminating the need to strip wires. The steady green led shows immediate readiness, switching instantly to bright red when ac voltage is detected. Thanks to the globally adapted measuring tip, you easily test sockets, switches, and junction boxes, or trace cable breaks and blown fuses. Rated for cat IV 1000V AC, this detector comes ready to work with 2 aaa batteries included.

Cat IV, 1,000 V
One-handed test
Optical signal
Before starting electrical installation work, electricians need to guarantee that their work environment is free of any live voltage. A voltage tester is required to test alternating electric fields or probable sources of error. The contactless Wiha voltage tester will give an initial indication of whether an area is live or not thanks to an optical signal. Once the tester is switched on, the permanently green LED indicates that the tester is ready for use. If a voltage is detected, the red LED lights up, which can also be easily seen in daylight. Two AAA batteries are required to operate the device. These are included in the delivery. With its push-on clip, the voltage tester snugly fits into any shirt or trouser pocket thanks to its handy size. The voltage tester is suitable for all socket variants worldwide thanks to its measurement tip adapted to international usage. Designed for CAT IV 1,000 V AC, the single-pole voltage tester complies with EN 61010-1/IEC 61326. The voltage tester should be tested on a known voltage source before and after every use to ensure it functions correctly.
