Adafruit Product Code: 71
This is a basic multimeter, I've played with it a bunch and I think its a great addition to a toolbox. It's low cost and simple to use with a big clear display and all the measurements you need:
- AC/DC Voltage measurement
- Current measurement, from 1uA up to 10A
- Beeping continuity test, and diode test
Comes with two probes as shown
Exact model may vary (we have two suppliers) but the quality and functionality is identical.
