Your multimeter is the most important diagnostic tool you own, and it’s not the place to cheap out. A $15 Harbor Freight multimeter will get you killed on industrial work - not because it reads wrong (usually) but because it’s not rated for the voltage categories you’re working in. CAT ratings exist for a reason: CAT III 600V for distribution-level equipment (panels, feeders, motors), CAT IV for utility service entrance and outdoor equipment.
Fluke is the gold standard. The Fluke 117 (CAT III 600V, $175-200) is the most popular residential/light commercial meter - it’s accurate, durable, has non-contact voltage detection built in, and the real-world ruggedness is proven over decades. Step up to the Fluke 179 or 289 for data logging and more advanced features. Klein and Ideal make credible alternatives at lower price points.
The features that actually matter in daily use: auto-ranging, true RMS (accurately measures non-sinusoidal loads like VFDs, dimmers, and switching power supplies), low impedance (low-Z) mode to eliminate ghost voltages on high-impedance circuits, and a bright display with a backlight. Ghost voltage is a real phenomenon on modern buildings with lots of parallel conductors - a low-Z meter will show you what’s actually energized.
