Cropico DO7 Micro Ohmmeter

The Cropico DO7 digital micro ohmmeter is a practical instrument for low resistance measurement, ideal for utilities use in the workshop, field or test facilities. It is of rugged construction, contained in a sealed ABS plastic case with lid and carrying handle.

The DO7 digital micro ohmmeter has many advanced features. Rechargeable batteries means real portability with more than 1 hour of continuous operation on the lowest ranges(10A), and 20 hours on all others. The Cropico DO7's internal charger will boost charge to 90% of full charge, switching automatically to a trickle maintenance charge. Warning LEDs illuminate when an open circuit lead condition is detected.
