Work horse clamps with increased performance and flexibility

374 and 375 True-RMS AC/DC Clamp Meters

The new Fluke 374 and 375 clamp meters offer improved performance perfect for many current measurement situa-tions. With True-RMS ac voltage and current measurements, the Fluke 374 and 375 can read up to 600 V and 600 A in both ac and dc modes. Additionally, both are compatible with the new iFlex™ flexible current probe (sold separately) which expands the measurement range to 2500 A ac and pro-vides increased display flexibility, ability to measure around awkward sized conductors and improved wire access.
