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
