SC46 True RMS Mini Clamp Meter by Fieldpiece

The SC46 True RMS Mini Clamp Meter with Temperature and Backlight packs the biggest punch in the SC40 series. With features that rival many full-sized clamp meters, this auto ranging DMM packs a ton of functions into a compact, easy to handle shape. It includes temperature and capacitance as well as a bright green backlight and True RMS for more accurate readings on non-sinusoidal AC waveforms. It also packs in most of the other HVACR ranges you use everyday. Some technicians use the SC46 as their everyday DMM, others as a back-up or second meter to get more testing done in less time. This mini-clamp was deigned to make your job easier, safer, and faster no matter where you choose to rank it in your bag.
