Precise AC DC Leakage Current Tester

The M700 AC/DC Clamp Milli-Ammeter (CE) or Precise AC DC Leakage Current Tester is accurate and sleek with a rugged and reliable design. The Precise AC DC Leakage Current Tester is capable of measuring 4-20 mA in control circuit and there are different internal opening diameters of the clamps. From small current leakage to high load currents, the Precise AC DC Leakage Current Tester can measure all currents in µA or ma while testing protection relays. The application area of the Precise AC DC Leakage Current Tester is automobile electronics and they can check earth leakage currents and small third harmonic leakage current from lightening arresters as well. There are special models for AC leakage clamps and AC/DC leakage clamps, and the Precise AC DC Leakage Current Tester can also be availed for clamps with multi meter functions, leakage current check and load current check in high voltage cables.
