Description

Hioki clamp sensors are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CT7040 Series compromise of 600A/6000A AC flexible current sensors in three different loop sizes that pair with the detachable Display Unit to measure large currents in crowded wiring and confined spaces.

A comment of Good Design Award 2016 “I was impressed with the high level of functionality combined with a compact design and a dustproof and waterproof enclosure as well as the high level of technical skill evident in the integration of multiple types of plastic and two cables. These appealing products also exhibit beautiful finish quality.” CAT IV 600 V, CAT III 1000 V
