The Smallest Multimeters – Compact Tools for Everyday Electronics

What Are Small Multimeters?

Small multimeters are pocket-sized or ultra-compact digital meters designed for portability while offering essential functionality. They typically measure essentials like voltage, resistance, and continuity—all in a form factor that fits your pocket or tool belt.

Fluke 101+

Key Features They Offer

Despite their size, many compact multimeters include:

  • Basic measurements: AC/DC voltage, resistance, continuity, and sometimes current.
  • Auto-ranging or manual-range capability.
  • Data Hold and sometimes a Backlit Display for easier reading.
  • Safety Ratings like CAT II or CAT III for basic electrical environments.
  • Durability with rugged housings built to withstand drops and field conditions.
