Description

Fluke 381 Remote Display TRMS Clamp Meter

All the bells and whistles. Be ready for anything


The Fluke 381 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 around a conductor, remove the display and walk across the room to operate controls or remove protective equipment, all while watching real-time readings.

 

Fluke 381 Comes Supplied With:

  • 18-inch iFlex™ flexible current probe
  • Coated instruction card
  • Safety information sheet
  • Soft carrying case
  • TL75 test leads
  • Five AA Alkaline batteries

The iFlex flexible current probe (included) expands the measurement range to 2500 A ac while providing increased display flexibility, ability to measure awkward sized conductors and improved wire access.

 

Key Features:

  • 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
  • The removable magnetic display can be conveniently mounted where it is easily seen
  • iFlex flexible current probe expands the measurement range to 2500 A ac
  • CAT IV 600 V, CAT III 1000 V
  • 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
  • Three-year warranty
  • Soft carrying case
