  • 60 kΩ resistance measurement with continuity detection
  • Min, max, average and inrush recording to capture variations automatically
  • Wireless technology allows the display to be carried up to 30 ft away from the point of measurement for added flexibility without interference with measurement accuracy
  • iFlex flexible current probe expands the measurement range to 2500 A ac while providing increased display flexibility, ability to measure awkward sized conductors and improved wire access
  • CAT IV 600V, CAT III 1000 V safety rating
  • Integrated low pass filter and state of the art signal processing allows for use in noisy electrical environments while providing stable readings
  • Proprietary inrush measurement technology to filter out noise and capture motor starting current exactly as the circuit protection sees it
  • Ergonomic design fits in your hand and can be used while wearing personal protective equipment
  • Removable magnetic display
  • Radio transmitter automatically turns off when the display is connected to the meter
  • Large, easy to read, backlight display

The Fluke 381 True-rms Remote Display AC/DC Clamp Meter w/ 18"-inch iFlex does everything you would expect from a clamp meter, and then lets you remove the display for even more flexibility. Now one technician can do jobs that used to require two people; clamp the Fluke-381 AC/DC Clamp Meter 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 with the Fluke 381 True-rms AC/DC Clamp Meter) expands the measurement range to 2500A AC while providing increased display flexibility, ability to measure awkward sized conductors and improved wire access.
