Basic electrical tests are made easy with Extech's pocket-sized digital multimeter, the MN30.

Unique to the MN30 is a smart AutoSensing function; this mode automatically detects the input and switches the multimeter to the correct mode (for example voltage or resistance measurements). It can be used to test AC/DC voltage to 600V, resistance from 1Ω to 10MΩ, tests continuity with a built-in beeper and includes a built-in non-contact voltage detector with range from 50 to 600V.

Working in the dark? The MN30 includes a built-in torch light to help you see where you're working. The meter has permanently-attached test leads and is powered by 2 x AAA batteries (included in the pack).

Additional features of the MN30 include a 4000 count LCD display, low battery indicator, automatic power off and overload indication.

This digital multimeter is CAT III 600V safety rated.
