Description

technical field [0001] The invention relates to a resistance measuring device, in particular to a device for measuring the surface resistance of a flexible sheet material, which belongs to the technical field of resistance measurement. Background technique [0002] With the development of microelectronics industry and fine chemical industry, the static electricity requirements for these industrial environments and equipment operating spaces are also getting higher and higher. Therefore, a large number of design requirements for preventing static electricity are put forward in the manufacture of textile materials, and then The coming surface resistance measurement related to electrostatic properties also puts forward higher requirements. [0003] The existing device for measuring the surface resistance of an object is composed of two parallel electrodes about ten centimeters long. This method has defects such as low measurement sensitivity, large influence of volume resistanc...
