Matco Tools introduces a new Automotive DMM (True RMS), the ADMM50. This tool has professional-quality features that help pinpoint engine problems (auto-ranging, auto shut-off, over-load protection); measures inductive rpm pickup and vehicle rpm (including coil-on-plug vehicles).

The tool’s 10 MegOhm impedance prevents damage to the ECU. It also tests alternator diodes, duty cycle, solenoids, breaker points, wiring, switches and more. It features automatic zero adjustment, reverse polarity protection, measures temperature in both C and F, and Min/Max and Hold buttons save retrieved data.
