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.

• 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
