Product overview: Fluke 381 Remote Display True RMS AC/DC Clamp Meter with iFlex®

What once took two people, now takes one

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.

The iFlex® Flexible Current Probe (included) expands the measurement range to 2500 A AC while providing increased display flexibility. With a cord that runs 6 feet, you can finally measure those tight spaces, awkward sized conductors and disorganized wires.

Other key features

  • 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
Safety Conformance: IEC/EN 61010-1:2001, 1000V CAT III, 600V CAT IV

Rated 1 out of 5 by from flex clamp does not do DC amps sucks need to make a product that does DC amps also with the flex amp contraption

Rated 5 out of 5 by from My most treasured possession I love my Fluke 381 more than my own children (kidding, I don't have kids). I use it daily in my work on boats, both for AC and DC. I never doubt the readings, and the remote display makes me the coolest tech on the dock. It gets borrowed often because it's so awesome. I can clamp the starter or alternator in the engine room, and take the remote display to the helm (except on the REALLY big boats). What usually takes two technicians, I can accomplish myself with my Fluke 381. My Fluke should get it's own paycheck. My only complaint is I really wish the iFlex did DC amperage. And I wish it were a little smaller. Unlike some other reviewers, I must be lucky because I don't think the battery consumption is bad. I replace them maybe every 2 months, and I use it on a daily basis.

Rated 5 out of 5 by from Another awesome Fluke Product I really enjoy using this clamp meter. I am in the industrial field and use the iflex to calibrate compressors. Without the iFlex, it would be impossible to get a meter around the motor leads inside the motor peckerhead.
