Megger DLRO10X Low Resistance Ohmmeter - Ductor. The Megger DLRO10X is a fully automatic ductor that will select the most suitable output current (up to 10A DC) in order to measure resistance values between 0.1 micro-Ohms to 2000 Ohms, across seven separate ranges. The BT51 is a stable, accurate, reliable, low resistance ohmmeter equally suited to precision laboratory applications and to applications in the field. The BT51 Low Resistance Ohmmeter makes measurements by passing a current through the conductor under test and also monitoring the voltage across it. Find great deals on eBay for megger meter.
