Description
Fluke 375FC True-RMS Clamp Meter
The Fluke 375FC True-RMS Clamp Meter can be used to measure current levels up 600A (AC and DC). By equipping an optional Fluke iFlex probe it is also possible to expand this range further up to 2500A (AC only). The integrated low pass filter and state of the art signal processing allows for use in noisy electrical environments while providing stable readings whilst proprietary inrush measurement technology filters out noise and captures motor starting current exactly as the circuit protection sees it.
