Digital earth resistance tester DY4100 is a new generation tester for electrician practice which is developed by DUOYI
in recent years. The circuit, structure and technique of traditional earth resistance tester have been improved and
thenew design is both fine-looking and practical. This one has more complete functions, higher accuracy,
more convenient and reliable for operation and more suitable for outdoor use with dust and wet proof structure.
It can test earth resistance of various earth systems including power systems, electric equipments, lightning conductors
as well as resistance value of low resistance conductor and AC voltage test.
