DLRO2
Accurate Measurements in Harsh Conditions
Equipped with a Noise Rejection Mode and Confidence Meter™, the DLRO2 ensures reliable results even in electrically noisy environments.
Safety and Versatility
With a CAT III 600 V/CAT IV 300 V rating and <600 V active protection, the device is safe for use in various industrial applications, including inductive load testing at 1 A.
User-Friendly Data Management
Features like the Difference Meter for comparative analysis, and Bluetooth connectivity for easy data transfer, make the DLRO2 both powerful and convenient. It also supports data export via USB and is compatible with the CertSuite Asset software for streamlined asset management.

The DLRO2 2 A Low resistance ohmmeter is a handheld instrument designed to give you fast, accurate, repeatable measurements, even in electrically noisy locations. The DLRO2 is the latest in a long line of instruments to proudly display the Ducter™ brand, the Ducter™ testers being as well-known and relied upon as Megger insunsulation resistance testers.
The DLRO2 can measure low resistance values across a wide range of applications, including railways, aircraft, and industry components. This tough device comes with a brand new ‘difference’ meter that allows repetitive measurements to be easily compared with an initial reference measurement. The difference meter also translates the percentage difference to a needle/pointer movement, making the changes clear to see.
If your applications require long test leads, then the DLRO2 can provide this without compromising test speed or safety. It has a dedicated long lead test to optimise the output, and this long test lead function is able to provide up to 1 A of test current into 4 ohms resistance. The DLRO2, with its optional cable reel test leads, is therefore ideal for testing wind turbine and avionic lightning protection applications.

FAQ / Frequently Asked Questions
It allows you to be able to compare multiple test results within the instument, you can also translate the results to a percentage difference.
It is a dedicated mode for the DLRO2X that optimises the output, the long lead test function is able to provide up to 1 A of test current into 4 Ohms resistance. The DLRO2, with its optional cable reel test leads, is therefore ideal for testing wind turbine and avionic lightning protection applications.
