CanNeed-OCTG-2000 Coating Thickness Gauge is used to measure the coating thickness in real time, save time and improve the quality of the product. Non-contact optical measurement technology is applied to product development, laboratory quality control and online production control. In the solar energy industry, optical coating industry, food packaging,as well metal packaging, are very good choice to improve the surface quality of products: appearance, adhesion, corrosion resistance, abrasion resistance, scratch resistance.
