Fluke 375 True-rms AC/DC Clamp Meter

With true-rms ac voltage and current measurements, the Fluke 375 Clamp Meter can read up to 600 V and 600 A in both ac and dc modes, and is capable of frequency measurement up to 500 Hz. Additionally, the 375 is compatible with the new iFlex flexible current probe (sold separately), which expands the measurement range to 2500 A ac.
