Megger DLRO100X & DLRO100XB Datalogging Micro Ohmmeters

Note: there are two versions of this product available. Both have identical functionality apart from their power source. Model DLRO100X is powered by AC line connection only, while model DLRO100XB is powered by both AC line and rechargeable batteries.

The mid-range models in Megger's DLRO100 series, these powerful micro ohmmeters are the upgraded version of the Megger DLRO100E/EB with additional features such as built-in memory storage and the option to use a DC clamp for circuit breaker testing with ground protection (clamp sold separately).

With the built-in memory storage of this unit, the DLRO100X and XB are perfectly suited for testing low resistance levels over a period of time. A dedicated continuous testing mode is included for this purpose; the unit will automatically cycle through tests until deactivated, storing results on its built-in memory alongside a time and date stamp. Once done logging, plug the unit into a PC via USB connection to download the data for further analysis.

The DLRO100X and XB also come with manual and automatic testing modes, high noise immunity for stable readings, smooth DC output for testing circuit breakers and much more.

Megger's DLRO100 units are built with safety in mind and are CAT IV 600V AC and 500V DC safety rated. It also comes built inside its own protective case with IP54 protection with the lid open and further IP65 protection when the lid is shut.
