Micro Ohmmeter DO7

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 1 hour of continuous operation on the lowest ranges(10A), and 20 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.

Micro Ohmmeter Features DO7:

  • True 4 terminal measurement eliminates lead resistance errors
  • 10A measuring current
  • Rechargeable batteries with built-in charger
  • Measuring ranges 600µΩ to 60Ω
  • Resolution 0.1µΩ on 600µΩ range
  •  0.8” LED display daylight viewable
  • Auto average of forward and reverse measurement
  • Remote start socket
  • All solid state design
  • Wide range of leads and accessories available
  • RS232 printer output
  • Protection up to 415Vrms at the measuring terminals,
  • Digital calibration and long scale length
  • 6,000 count
