Fluke 376 True-rms AC/DC Clamp Meter with iFlex™

The Fluke 376 Clamp Meter offers improved performance perfect for a wide range of current measurement situations. With true-rms voltage and current measurements, the Fluke 376 can read up to 1000 V and 1000 A in both ac and dc modes.
Additionally, the Fluke 376 includes the new iFlex™ flexible current probe, which expands the measurement range to 2500 A ac while providing increased display flexibility, ability to measure around awkward sized conductors and improved wire access. The Fluke 376 is the direct replacement for the Fluke 337 Clamp Meter.
