Rugged digital micro ohmmeter for low resistance measurement.

- High accuracy from 600 microhms to 60ohms ranges
- LED display for daylight viewing
- Mains / rechargeable battery operation

 

 

The 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 40 minutes of cumulative operation on the lowest ranges, and over 12 hours on all others. The 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.
