CM4375-50 AC/DC CLAMP METER
Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CM4375-50 is a 1000 A AC/DC True RMS clamp meter that features a uniquely designed slim jaw that lets you easily get into the narrow gaps between cables in crowded electrical distribution boxes without fear of damaging the cables or the clamp meter. The broad IP54 dustproof and waterproof enclosure to enable professionals to work quickly in challenging situations including the development, repair, and maintenance of equipment and devices such as electric vehicles. Additionally, the high-voltage DC measurement capability of up to 2000 V (*1) is ideal for the clamp maintenance inspections of electrical and solar power equipment.
