Fluke 374 True-rms AC/DC Clamp Meter

The Fluke 374 True-rms Clamp Meter can read up to 600 V and 600 A in both ac and dc modes. Additionally, the 374 is compatible with the new iFlex flexible current probe (sold separately), which increases the measurement range to 2500 A ac and provides increased display flexibility, and improved wire access.
