Low cost and pocket-sized, this digital multimeter is a great solution for quick and easy electrical measurements.

One of the smallest digital multimeters on the market (less than 3/8" thick and weighs less than 3oz), the PM51A is simple to operate, portable and has built-in test leads. Tests are selected via a thumb wheel, and results are shown on the multimeter's big digit LCD screen.

Despite its tiny size, the PM51A is more than capable of carrying out a wide variety of electrical measurements. It can test AC/DC voltage to 600V, resistance to 40MΩ, frequency to 1MHz and capacitance to 3000μF plus can test continuity with an audible buzzer.

This digital multimeter is autoranging (automatically selects the appropriate range for a test), will automatically power itself down when left idle to converse battery life and comes with a data hold function that temporarily freezes the last value taken on the screen.
