Description

A heavy hammer type surface resistance tester

technical field

The utility model relates to the technical field of antistatic products, in particular to a heavy hammer type surface resistance testing instrument. the

Background technique

In modern industrial production, as the requirements for precision production are getting higher and higher, static electricity has a great impact on the quality of products (especially electronic products). Therefore, many fields require anti-static production operations, and workers generally need to wear anti-static Electrostatic work clothes and work shoes, but even so, it cannot fully guarantee that the static electricity of the human body and equipment meets the requirements. In the field of anti-static, measuring the surface resistance of anti-static products is one of the most commonly used and effective methods. By measuring the surface resistance, the anti-static ability of anti-static products can be detected. For products that do not meet the requirements of static detection, corresponding measures should be taken Measures to avoid adverse effects of static electricity on production operations and the product itself. the
