Fluke 381 Remote Display True-RMS AC/DC Clamp Meter with iFlex

Fluke 381 Remote Display True-RMS AC/DC Clamp Meter with iFlex delivers flexible, safe measurement capabilities for electricians, maintenance technicians, and industrial engineers working on energized electrical systems. With its detachable wireless display and flexible iFlex current probe, it helps users capture accurate readings in tight, crowded panels without needing a second person.

The clamp meter is designed for demanding electrical environments, supporting AC and DC voltage, current, resistance, and frequency measurements. Its integrated low pass filter and advanced signal processing help maintain stable readings even in noisy conditions, while true-RMS measurement supports accurate results on non-linear loads.

Key Features

Benefits

Do more with one technician

• Remote display allows a single user to clamp the conductor, step away to operate controls, and still see real-time readings

• Reduces the need for a second person during testing, improving productivity on site

Improve safety and working distance

• Wireless display helps keep the operator farther from live conductors and energized gear

• Magnetic mount enables hands-free viewing while the user manipulates controls or PPE

Handle tight and complex installations

• iFlex probe makes it easier to measure in crowded panels and around large or irregular conductors

• Long probe lead helps reach disorganized wiring without straining or repositioning equipment

Get accurate readings in real-world conditions

• True-RMS measurement ensures reliable data on modern loads such as drives and electronic equipment

• Low pass filter and advanced signal processing provide stable readings where electrical noise is present

Built for professional use

• CAT III 1000 V / CAT IV 600 V ratings support use on a wide range of electrical systems

• Robust handheld form factor and included carrying case support field use and transport
