DUOYI DY4100 digital megohmmeter grounding resistance measurement soil resistivity meter megohmmeter tester grounding 0-2000 ohm insulation

The digital grounding resistance tester DY4100 is a new generation of electrician practice tester developed by Duoyi in recent years. The circuit, structure and technology of the traditional grounding resistance tester have been improved, and the new design is both beautiful and practical. The machine has more complete functions, higher precision, more convenient and reliable operation, and the dust-proof and moisture-proof structure is more suitable for outdoor use. It can test the grounding resistance of various grounding systems such as power systems, electrical equipment, and lightning conductors, as well as the resistance value of low-resistance conductors and AC voltage testing. Ground resistance measurement range is 0.01Ω to 2000Ω with 0.01Ω resolution. Data hold, low battery warning, with test leads, auxiliary ground rod, (batteries not included) Specifications:
