HIOKI CM4375 AC/DC Clamp Meter
Easily Get Into Tight Spaces
Innovative Jaw Provides Remarkable Accessibility
Inrush Current Measurement Accuracy Guaranteed

OVERVIEW
Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CM4375 is a 1000A 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 -25°C to 65°C operating temperature range and 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 1700 V (*1) is ideal for the clamp maintenance inspections of electrical and solar power equipment.

CAT IV 600 V, CAT III 1000 V

Made for Real-World Situations Uncompromising Design
Panel overcrowding is commonly found in many power distribution breakers and termination boxes. The newly designed thin sensor gets into even the most limited spaces. Eliminate the issues of trying to find the right wire or forcing the clamp around thick cables.

Key Features
  • CAT IV 600 V, CAT III 1000 V
  • When using P2000: CAT III 2000 V, CAT IV 1000 V
  • Easily get into tight spaces between cables thanks to thin sensor structure
  • Measure DC voltages of up to 2000 V (*1) for open voltage inspections of solar panels
  • Automatic AC/DC function helps boost work efficiency, Measure up to 1000 A
  • Simultaneously measure inrush current in RMS and crest values
  • Easily transfer measurement data to your smartphone or tablet by using our free app GENNECT Cross or to an Excel® file. (*2)
  • Harmonic analysis from 1st to 30th order with GENNECT Cross (*2)
*1:When using the optional DC High Voltage Probe P2000. The clamp meter itself is capable of measuring up to 1000 V DC.
*2:Wireless Adapter Z3210 is necessary.
