  • Our most sensitive current probe, accurately measuring down to 5 milliamps.
  • Ideal for measuring leakage current and ground faults.
  • Large jaws allow clamping around all three phases to net out the currents and find the leakage current.
  • Dual measurement range allows measuring up to 200 amps in high accuracy, so it is useful for all small to mid-size AC loads.
