The DO7e is a practical low cost micro ohmmeter for low resistance measurement, ideal for utilities in the workshop, field or test facilities. This micro ohmmeter is of rugged construction, contained in a sealed ABS plastic case with lid and carrying handle.

The DO7e microhmmeter has many advanced features, including protection up to 415 volts rms at the measuring terminals, digital calibration and long scale length, 6,000 count. The measuring ranges may be automatically or manually selected.

Automatic Power Off ensures maximum battery life. The internal charger will boost charge to 90% of full charge, switching automatically to a trickle maintenance charge.
