Overview:
The grounding resistance tester is a professional instrument for testing the grounding resistance of electrical equipment.It improves the circuit,structure and process of the traditional grounding resistance tester,in addintion,the style is beautiful and pratical,the function is more complete,the accuracy is higher,the operation is more convenient and reliable,the dust-proof and moisture-proof structure is more suitable for feild use.It can be used for grounding resistance values of various power systems, power equipment,lighting protection equipment and other grounding systems,as well as AC voltage.
