Di-Log DL9050N Insulation/Continuity Tester
The Di-Log DL9050N Insulation/Continuity Tester gives electricians and maintenance engineers a reliable way to carry out insulation and continuity checks. It combines clear digital readings with simple controls, so daily testing tasks become faster and easier. Its rugged double moulded housing also helps protect the tester in demanding work areas.
With four insulation test voltages, the unit supports a wide range of electrical testing jobs. The Di-Log DL9050N measures insulation resistance up to 4000MΩ and performs continuity testing from 0.01Ω to 400Ω. In addition, the tester delivers a 200mA continuity test current that complies with BS EN 61557 standards.
Reliable Performance
Large dual LCD readings allow users to view measurements clearly in different lighting conditions. A built-in bar graph display gives fast visual feedback during testing, while the hold function helps keep readings visible when recording results. The Di-Log DL9050N also includes lead zero adjustment to improve accuracy during low resistance testing.
Live circuit detection improves safety during operation and helps prevent incorrect testing conditions. The output voltage lock function keeps a stable voltage during insulation tests, which supports consistent readings. Furthermore, the auto power off feature reduces battery drain during long working days.
Built For Daily Electrical Testing
Designed for site and industrial use, the tester includes a strong carry case and durable outer housing for added protection. The compact body remains easy to handle while still providing a large display and clear controls. Six supplied AA batteries power the unit for convenient portable operation.
Electrical contractors, inspection engineers and maintenance teams can use the Di-Log DL9050N across many installation and servicing tasks. Its CAT III 1000V safety rating supports work on commercial and industrial systems. As a result, users receive dependable insulation and continuity testing in one practical handheld instrument.
