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 TRMS AC/DC clamp meter can measure 1000 A AC/DC with the fixed jaw and the 18" iFlex flexible current probe expands the measurement range up to 2500 A AC. The Fluke 381 has a AC/DV volt range up to 1000V. It also measures frequency and continuity.

Fluke 381 clamp meter's remote displayRemote Display

The Fluke 381's remote display (like the Fluke 233 Digital Multimeter) allows you to safely and conveniently read measurements from up to 30 ft. away and can also be magnetically mounted. The detachable remote display features a Hold, Min/Max and a Backlight button. The backlight button is a great feature that illuminates the digital display in dark spaces. 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.
