The Megger DLRO-H200 Hand-Held 200A Micro-Ohmmeter is engineered for precision and safety, offering a streamlined solution for measuring the resistance of high-current links such as circuit breaker contacts and bus-bar joints. This instrument embodies the key principles of safety, ease of use, and versatility, making it an indispensable tool for technicians in various settings.

A standout feature of the DLRO-H200 is its capability to perform measurements using the innovative DualGround™ method. By grounding the test object on both sides during the assessment, this method enhances safety and efficiency, allowing for a faster and easier workflow. This functionality is particularly valuable in environments where safety and accuracy are paramount.

Designed with the demands of fieldwork in mind, the DLRO-H200 combines ruggedness with lightweight construction, making it ideally suited for use in substations and similar locations. It is equipped with a robust rubber holster that enhances its durability and resilience in harsh conditions. The device’s portability is complemented by its ability to perform a full day of testing without the need for recharging, ensuring uninterrupted operation.

Additionally, the DLRO-H200 boasts advanced connectivity features. It can store up to 190 test values and facilitates seamless transfer of test data to a PC via Bluetooth. This wireless capability also extends to a supplied wireless headset, which can provide audible pass/fail signals based on user-defined limits during testing. This feature allows technicians to receive immediate feedback while maintaining focus on the task at hand, further optimizing the testing process.
