Hioki-CM4141 AC CLAMP METER

Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CM4141 is a 2000 A AC 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 -25°C to 65°C operating temperature range and IP50 dustproof and waterproof enclosure to enable professionals to work quickly in crowded electrical distribution panels. The high current measurement capability makes it especially useful for industrial applications.
