What is a Surface resistance meter?

A surface resistance tester is a machine that measures the resistance value of anti-static products. Various measurements are possible by using the optional probe and stainless steel plate. Objects that are insulators are always charged with static electricity, causing deterioration and causing ground faults and electric shocks. Therefore, by measuring the surface resistance and the insulation resistance value, it is possible to predict the deterioration of the object over a long period of time. In addition, it is possible to measure how much water is contained in water-based paints and concrete that contain water and harden when the water is removed during drying. Especially in the film formation process called chocolate type, in which the water solvent volatilizes and forms a film, moisture control becomes a major issue, so it is used as a moisture control process.

Application of Surface resistance meter

The surface resistance tester is mainly used for periodic inspections in a clean room where electronic parts are manufactured as a work environment measurement. In addition, as process control and quality control, the water content on the surface of the product can be measured using the resistance value, so it can be used to check the dry state of paint and concrete. Many portable types use probes, and can be grounded by installing two probes on the surface to measure the resistance between two points on the surface, or by installing one probe and touching the surface with the other probe. You can measure the resistance. In addition, the surface resistivity can be measured by attaching a surface resistance tester to the surface without using a probe. In addition, volumetric resistance can be measured by placing a stainless steel plate on an insulator plate and placing one of the probes on the stainless steel plate and the other on the object to be measured.
