Fluke 381 Remote Display AC/DC True-RMS Clamp
The Fluke 381 Remote Display AC/DC True-RMS Clamp 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 flexible current probe (included) expands the measurement range to 2500 A ac while providing increased display flexibility, ability to measure awkward sized conductors and improved wire access.
- 1000 AC/DC current measurement with fixed jaw
- 2500 AAC/DC current measurement with iFlex flexible current probe
- 1000 V AC/DC voltage measurement
- True-RMS AC voltage and current for accurate measurements on non-linear signals
- Frequency measurement to 500 Hz with both jaw and iFlex
- 60 kΩ resistance measurement with continuity detection
- Min, max, average and inrush recording to capture variations automatically.
