Miniature Digital Ammeter

Please note: This version of the Miniature Digital Ammeter is no longer available, but have no fear! An updated version is in the works.

Make current measurement simple, clear, and unintimidating. The Miniature Digital Ammeter is designed to clip directly into student-built circuits, making it especially approachable for beginners. It comes with alligator clip leads, has a small, elegant design, and fits neatly into almost any setup—so students can focus on understanding current instead of wrestling with equipment.

With a bright digital display and straightforward operation, the meter auto-calibrates, shows polarity with a plus/minus indicator, and automatically powers off to conserve battery life. A 3V lithium battery is included, so it’s ready to use right out of the box.
