If you're looking for one of the best multimeters, they're proud to now offer Adafruit's personal favorite! The Extech EX330 "12 Function Mini MultiMeter + Non-Contact Voltage Detector. Autoranging DMM with NCV detector and Temperature function". This product is the winner of EEVBlog Multimeter Shootout (Extech press release) & Dave's site here and on top of that, its been Adafruit's daily-use multimeter for over 3 years. It's compact, has auto-off, tons of features and a temperature probe for checking thermal properties, soldering iron calibration and perhaps even a DIY reflow control
Compact auto-ranging multimeter features extra large 4000 count display and built-in non-contact AC voltage detector. Advanced function include Frequency (nice for checking UART baud rates, crystal oscillators), Duty Cycle, Capacitance and Temperature (is your power supply overheating?), Diode test and continuity beeper. Rubber holster protects meter. UL listed Cat III - 600V. Includes test leads, Type K temperature probe, two AA batteries and tilt stand. UL listed. Large display and a host of features.
