Megger DLROs Built for Reliability

Posted by Protec Tech Team on

Contact Us Nowlow resistance ohmmeter can be used to identify many of the issues that stem from poor electrical connections. Contact resistance is a term used to characterize the quality of an electrical connection. Electrical bonds are a component of everything that requires a connection to an electrical path such as junction boxes,bus work, circuit breakers and switches to name a few.  Poor connections can lead to excessive heating, premature equipment failure and damage to the electrical system itself. A good testing and maintenance program will include a low resistance ohmmeter to ensure the quality of electrical connections. 


Megger DLRO or digital low resistance ohmmeters are built to endure tough working conditions, while offering accurate and reliable test information regarding electrical connections.
