Description

The Fluke 381 True RMS AC/DC clamp meter does everything you would expect from a clamp meter including letting you remove the display for even more flexibility. Now one technician can do jobs that used to require two people. Clamp the Fluke 381 around a conductor, remove the display and walk across the room to operate controls or remove protective equipment, all while watching real-time readings.

The new iFlex flexible current probe (included) expands the measurement range of the Fluke 381 True RMS AC/DC clamp meter to 2500A AC while providing increased display flexibility, ability to measure awkward sized conductors and improved wire access. An integrated low pass filter and state of the art signal processing allows for use in noisy electrical environments while providing stable readings. Fluke 381 True RMS AC/DC clamp meters feature CAT IV 600V and CAT III 1000V ratings and its ergonomic design fits in your hand and can be used while wearing protective equipment.

The Fluke 381 True RMS AC/DC clamp meter ships complete with:

  • 18" iFlex current probe
  • Instruction card
  • Safety information sheet
  • Soft carrying case
  • Test leads (TL75)
