Beha-Amprobe PM51A Pocket Multimeter Details

One of the smallest multimeters on the market, Amprobe's PM51A is just 3/4 of an inch thick and is actually small enough to fit inside a shirt pocket! It's also low cost, performs accurate measurements and is a great instrument for those wanting to carry out basic electrical measurements.

An autoranging digital multimeter, the Amprobe PM51A can be used to measure AC/DC voltage up to 600V, resistance to 40MΩ, frequency to 1MHz and capacitance to 3000μF. Each function has several ranges and the PM51A will automatically select the correct one for the measurement type.

Despite its tiny size, the PM51 still contains a few advanced functions such as data hold (freezes the last value taken), a large screen, low power consumption and audible continuity testing.

This digital multimeter is CAT II 600V and CAT III 300V safety rated.

Amprobe PM51A Pocket Multimeter Key Features
