Biddle DLRO Digital Low Resistance Ohmmeters

  Biddle Digital Low Resistance Ohmmeters (DLRO) are a family of highly accurate instruments that provide a simple, practical and reliable means of making low-resistance tests in the field. They also are ideal for production quality control. They operate on the four-wire measurement principle, thus eliminating lead and contact resistances. With basic accuracies of ±0.25% and resolution down to 0.1 µΩ, they are nonetheless designed to be rugged and portable for use at the job site. A variety of optional test leads and calibration resistance standards are offered for use with DLROs.


  • Resolution to 0.1 µΩ on 599.9 µΩ range
  • Standard accuracy of ±0.25%
  • Digital readout
  • Resolution as fine as 0.1 mΩ
  • Standard accuracy of ±0.25%
  • Kelvin-type, four-wire measurement eliminates errors caused by lead and contact resistances.
  • Digital readout with automatic zero circuit eliminates field test inaccuracies.
  • Broad line of test leads is available to simplify and enhance data collection.


   Operation is simple: just connect the leads, turn the instrument on and read the measurement directly from the digital LED display. No warm-up is required. Typical applications include measuring the resistance of:

  • Switch and circuit breaker contacts
  • Transformers and generators
  • Motor windings
  • Busbar and other joints
  • Aircraft, rail and pipe bonds
  • Cable splices, welds and fuses
  • Metal alloys
  • Graphite electrodes and other
  • Composites
  • Wire and cable
