1mA to 1000A AC Leakage to Load Current Clamp
Meter with 10 µA Resolution in Innovative Flip Design

Hioki clamp meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The 3293-50 features a thin and compact clamp core that can measure current between a wide 30mA to 1000A range. The clamp meter is constructed so that the position of the display panel can be adjusted to suit the measuring location, and the back light makes it easy to use even in dark locations.


  • Measure for leakage current and load all with the same device
  • Innovative flip clamp design
  • Flip display to see measurement readings from any angle
  • 1mA to 1000A accuracy guaranteed, 6 ranges and bar graph display
  • Measure and display only the leakage current of commercial frequency components using the filter function
