AC CLAMP METER CM4141-50
True RMS 2000 A AC Clamp Meter
Innovative Current Sensor Design - Easily Get Into Tight Spaces
Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CM4141-50 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 high current measurement capability makes it especially useful for industrial applications.
