Buying Guide
True RMS multimeters give accurate readings on complex signals. They’re safe and fast for home, car, or industrial work.
- Measurement Range: Pick a meter that handles your needs. Most measure up to 600V–1000V AC/DC and 10A–20A current. Check if it also tests resistance, capacitance, or temperature.
- Auto-Ranging: No dial needed—just auto-ranging picks the right setting. Saves time and cuts errors. Some models add manual mode for fine control.
- Safety Features: Look for CAT III or CAT IV ratings to handle surges. Double fuses and drop-proof builds (like 6.5–13 feet) protect you and the tool.
- Display Quality: A backlit color screen or large LCD makes readings easy in dim light. Models like the Fluke 87V MAX or FS899L shine here.
- Battery Life: Rechargeable via USB-C or long-lasting batteries (up to 800 hours) keep you working. No mid-job shutdowns.
- Durability: Tough rubber casings and IP67 waterproof ratings (like the Fluke 87V MAX) handle rough jobs.
