Beha-Amprobe DM78C Credit-Card Sized Digital Multimeter
Measuring just 130 x 77 x 18mm, the Beha-Amprobe DM78C is one of the smallest digital multimeters available on the market.
Suitable for any basic electrical measurement, the DM78C can measure DC and AC voltage to 600V, resistance to 34MΩ and can check continuity (with audible buzzer) and diode. The multimeter is supplied as standard with a set of integrated test leads for measurement.
Measurement results are displayed on the DM78C both as a numerical reading and also as an analogue bargraph on the multimeter's 3200 count display. This value can be held on the screen using the data hold button, making jotting down measurement results easier.
When left idle, the DM78C will automatically power itself down to conserve battery life.
