Megger DLRO10HD with KC1-TL3-C Kelvin Clips

Overview

Megger's DLRO10HD with KC1-TL3-C Kelvin clips is a heavy-duty low-resistance ohmmeter designed for precision testing in laboratory and field environments. 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 minimizes cool-down time between tests. The unit operates from either rechargeable battery or mains power, making it suitable for continuous repetitive testing and portable field deployment. High input protection to 600 V prevents damage from inadvertent connection to line or UPS voltage.

The supplied KC1-TL3-C Kelvin clips (3 m) enable four-wire measurement technique, providing superior accuracy for low-resistance measurements. Applications range from railways and aircraft maintenance to component resistance testing across diverse industries.
