Megger DLRO100 Digital Low Resistance Ohmmeter



Megger’s newly introduced DLRO100 series presents a revolutionary range of 100 A digital low resistance testers showcasing unmatched features. This series is distinct in providing CAT IV 600 V safety, operational IP54 ingress protection against dust and water, along with the incorporation of light, rapid charging, Li-ion battery technology in a continuous 100 A low resistance tester framework. The DLRO100 is highly adaptable, making it suitable for a wide array of applications such as switchgear, circuit breaker contact resistance, bus bar and cable joints, wire and cable resistance, lightning conductor bonding, welded joints, and ground connections and joints, especially beneficial in locations devoid of line power.

In developing the DLRO100 series, Megger has made no compromises, combining an exceptional set of features that include DualGround™ testing, adjustable current ramping, and high noise immunity, with the ability to carry out high-power 100 A continuous testing and remote control operation. Despite the robust capabilities, the design remains compact and lightweight.

The DLRO100 series includes three models:

  • DLRO100 E or EB: This base model can operate on line power and is also available in a battery-powered version alongside AC power, covering fundamentals with high efficiency.
  • DLRO100 X or XB: The mid-range variant builds on the base model by adding data storage and DualGround™ testing capabilities.
  • DLRO100 H or HB: The premium model extends the features of the E and X models by incorporating asset tagging (using the DLRO100 Asset Tag Windows app), Bluetooth® downloading, and USB for remote operations.

All models in the series are CAT IV 600 V rated and capable of testing currents ranging from 10 to 110 A, offering a versatile solution tailored for comprehensive testing needs.
