Hasegawa HSF-7 High and Low Voltage Detector

Overview

The Hasegawa HSF-7 is a portable high- and low-voltage detector designed to confirm the presence or absence of voltage in electrical circuits and equipment. It is widely used in industrial and commercial environments, construction sites, electrical maintenance and utility applications where electrical hazards must be managed safely.

The HSF-7 distinguishes between voltage levels through clear sound-and-light indication: low voltage is shown by intermittent sound and light, while medium voltage is shown by continuous sound and light. Covering a wide AC range from 80 V to 7000 V and featuring a firm, secure grip, it is a dependable everyday safety tool for electrical workers.
