Fluke 381 Remote Display True-RMS AC/DC Clamp Meter


The iFlex Flexible Current Probe expands the measurement range to 2500 Amps AC while providing increased display flexibility. With a cord that runs 6 foot, you can finally measure those tight spaces, awkward sized conductors and disorganized wires. Now one technician can do jobs that would otherwise 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.

  • Wireless technology allows the display to be carried up to 30 foot away from the point of measurement for added flexibility without interference with measurement accuracy
  • The removable magnetic display can be conveniently mounted where it is easily seen
  • 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 protective equipment
  • Radio transmitter automatically sets the correct measurement range so you do not need to change the switch positions while taking a measurement
