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

Key features

Wireless technology allows the display to be carried up to 30 ft. away from the point of measurement with measurement accuracy

Removable magnetic display can be 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

Other key features

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
