The Fluke i3000s Flex is an ac current clamp utilizing the Rogowski principle. It can be used to measure currents up to 3000 A when used in conjunction with oscilloscopes, recorders or data loggers. The flexible and lightweight measuring head allows quick and easy installation in hard to reach areas.

  • Three ranges: 30 A, 300 A & 3000 A, 1, 10 or 100 mV/A output
  • Ideal for current measurement on thick and hard to reach conductors without breaking the circuit
  • Maximum conductor diameter 178 mm
  • CAT III 600V safety rating
