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.

• Wireless technology allows the display to be carried up to 30 ft. away from the point of measurement for added flexibility without interference with measurement accuracy
• The removable magnetic display can be conveniently 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
• 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
• Soft carrying case
• Safety Conformance: IEC/EN 61010-1:2001, 1000V CAT III, 600V CAT IV
