The Sample Testing System ST4 was designed as a bench unit for laboratory and R&D use, delivering precise inspection of transparent, such as PE, PP, PS, PC, films, sheets or plates, as well as non-transparent surfaces, such as steel, paper, textiles etc.

The system examines the material for irregularities, contamination, gels, fish eyes, scratches, holes etc. with high resolution.

Two lighting techniques can be applied depending on the material. The transmission mode is used for transparent material whereas the reflection mode is applied for non-transparent material.

For the scanning process the testing material is fixed on a frame which automatically moves it with highest precision between the lighting unit and the line camera in case of transparent material, or in front of the lighting unit and the camera in case of non-transparent material.

Software

The system software is user friendly, menu-driven, using the latest Windows version as operating system, e.g. XP Professional.

The scanned sample can be precisely analysed, classifying detected defects in different sizes and shapes, and counting all defects with an option for statistical evaluation per defined area (m², ft² etc.).

The software has a "teaching"-function which allows the system to "remember" defined defect types.

Different tables, graphs and images can be reported and printed by the system, or alternatively transferred via Ethernet or Modbus.
