Coating Thickness Gauge

The Coating Thickness Gauge is a high-precision contact-type thickness measuring instrument designed for accurate determination of thickness for films, papers, foils, nonwovens, and sheet materials.

The instrument strictly follows standardized contact area and measuring pressure requirements to ensure reliable and repeatable results, while also supporting non-standard customization to meet special testing needs.

With automatic lifting and lowering of the measuring head, real-time statistical analysis, and touchscreen operation, the system effectively reduces human-induced measurement errors and is suitable for both laboratory testing and production quality control.

Application
