The most powerful models in Megger's DLRO100 series, the DLRO100H and DLRO100HB are high accuracy, low-resistance ohmmeters suitable for use in a wide variety of different electrical applications.

There are some differences between this and the four other models in the DLRO100 series. The main differences are that these products include a remote control option (control remotely via USB on your PC or laptop), asset tagging (making it easier to manage your testing) and come with Bluetooth wireless communication for easier transfer of your measurement data.

Up to 220 time and date stamped records can be directly stored on the DLRO100H/HB's memory and then transferred to PC via USB or Bluetooth connection. With dedicated memory available you'll be able to determine how resistance changes over a period of time and log every single reading, complete with the time that the reading was actually taken.

Megger DLRO100 series models have three measurement modes: manual, auto and continuous. In manual mode, the user must start the test themselves after connecting test leads to the object under test. In automatic mode, the user selects the desired current, then connects the leads before the tester activates the test itself. Finally there's continuous mode which will start continiously performing test cycles until the user actually stops the procedure.

You can expect even more from these testers including a large-size, backlit LCD screen, Dual Ground technology (requires optional DC clamp to enable circuit breaker testing with ground protection) and an ultra-tough, rugged and weatherproof casing.
