Adjustable sensitivity voltage tester

The KEHIPI AC-4 is a non-contact AC voltage detector pen designed for electricians and technicians who need to verify live circuits without direct contact. It offers two selectable measurement ranges of 12-1000V and 48-1000V, covering socket voltages from 110V to 250V AC. Automatic selection across three sensitivity levels helps match the tool to the task at hand.

Pocket clip and CAT safety ratings

Built from ABS and PVC materials, the tester body resists wear and includes a pocket clip for secure carrying on a belt or shirt. It meets CE CAT III 1000V and CAT IV 600V standards, indicating suitability for fixed installation and distribution-level measurements. Audible and visual alarms activate when voltage is detected, while a live/neutral wire distinction function works at close range.

Integrated flashlight and battery management

A white LED flashlight illuminates dark work areas such as panels or cable trays. A low-voltage indicator warns when the internal battery needs replacement, and an auto power-off function extends runtime between changes. These features reduce downtime and keep the tool ready for the next job.
