Overview
The Fluke
381 is the first clamp meter with a detachable,
remote display and iFlex flexible current probe for easier, faster,
safer measurements.
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.
The iFlex current probe (included) expands the
measurement range to 1500 Amps AC while providing increased display
flexibility, ability to measure awkward sized conductors and
improved wire access.

Features and Benefits
- Wireless technology allows the display to be carried up to
30 feet away from point of measurement for added flexibility
without interference with measurement accuracy.
- The removable magnetic display can be conveniently mounted
where it is easily seen.
- True Rms AC Voltage and Current for accurate measurements on
non-linear signals.
- iFlex™ flexible current probe
expands the current measurement range to 2500A AC.
- 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.
- IEC/EN 61010-1-2001, CAT III 1000V, CAT IV 600V.
- Ergonomic design fits in your hand and can be used while
wearing protective equipment.
- State of the art signal processing allows for use in noisy
electrical environments while providing stable readings.
- Large easy to read backlit display.
- Radio transmitter automatically sets the correct measurement
range so you do not need to change switch positions while taking
a measurement.
- 3-year warranty.
