2. Film and Sheet Material Manufacturing Inspection

Conduct non-destructive thickness measurements on delicate plastic films, foils, or composite sheets used in electronics, medical, or specialized industrial applications. The low measuring force prevents damage to sensitive surfaces.

Problem Solved

Maintaining precise film thickness is essential for functional performance, optical properties, barrier characteristics, and structural integrity of thin-film products.

3. Textile and Non-Woven Fabric Analysis

Accurately measure the thickness of textiles, non-woven fabrics, and compressible materials without causing significant compression or distortion. The 0.01 mm resolution provides fine detail for material characterization.

Problem Solved

Verifying the specified thickness of fabrics is crucial for product consistency, insulation properties, absorption rates, and overall textile quality in production.
