The Klein Tools MM700 outperforms the Fluke 117 in voltage range (1000 V vs 600 V per Klein spec) and adds temperature measurement, giving it a higher feature score. However, the Fluke 117’s low 10 MΩ input impedance reduces ghost‑voltage errors (Fluke spec) and its lighter 0.5 lb body is easier to carry (Wirecutter). For electricians focused on NCV and ghost‑voltage accuracy, the Fluke remains...
