Buying Guidance
Choose the Megger DLRO10-NLS if you need a reliable low resistance tester for industrial maintenance, laboratory work, production testing, or field applications and you want the flexibility to select your own test leads.
If you specifically need a package with leads included, this no-lead model is not the right choice. But if you already have compatible leads or prefer custom accessories, the NLS version is the more flexible option.
