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.
