Device for testing surface resistance of non-metal material

The invention relates to a device for testing surface resistance of a non-metal material. The device comprises an insulating shell and also comprises a gravity object in the insulating shell, a wire and an electrode insulator located in the insulating shell. The device also comprises a supporting electrode pair and a detecting electrode pair outside the insulating shell. The device also comprisesa wire female connector and an insulating handle on the insulating shell. The gravity object, the electrode insulator, the support electrode pair and the detecting electrode pair are sequentially stacked. One end of the wire is connected to a wire female connector, and the other end is connected to the supporting electrode. The testing device has the advantages of simple structure and convenient operation. The test device is just placed on the surface of an object to be tested in operation, the surface resistance value of the non-metal material can be accurately measured, a measurement resultis accurate, the influence
