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
Key features
- Wireless technology allows the display to be carried up to 30 ft. away from the point of measurement with measurement accuracy
- Removable magnetic display can be 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
