Clamp Meters



DCM301 DCM301DCM301

CAT.IV, AC current measurable max. 1000A

  • The CT shape makes it easier to clamp cable in crowded.
  • An electric field (EF) function is incorporated in the tip of the CT to enable detection of about AC 90V or more.
  • Large, easy-to -press HOLD button.
  • Equipped with LED light to illuminate the measurement target.
