Megger DLRO10HD Low Resistance Ohmmeter

Overview

Megger's DLRO10HD is a heavy-duty low-resistance ohmmeter combining rugged construction with accuracy and ease of use. Capable of delivering 10 A into measurements up to 250 megohm and 1 A into measurements up to 2.5 ohm with 60-second test duration, it offers minimal cool-down time between tests. The unit operates from either rechargeable battery or mains power, making it suitable for continuous repetitive testing in production lines or field environments. Equally at home in the laboratory or on the bench, the DLRO10HD can operate from mains supply even if the battery is completely depleted.

Applications range from railways and aircraft to general component resistance testing across diverse industries. High input protection to 600 V prevents damage from inadvertent connection to line or UPS voltage.
