Model 381 AC/DC
True RMS Clamp Meter with iFlex™ and Detachable Remote Display |
| |
|
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.

- 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.
