APL

The AS200 uses optical image analysis to identify, mark, count, and classify dirt and spots on paper, with automatic sample feeding and stored results.

01

Overview

The AS200 Paper Dirt Analyzer uses a high-resolution digital camera and a low-distortion measurement lens to capture paper images under defined illumination. It identifies and marks dirt and spots, then measures, counts, and classifies them by configured criteria.

An automatic feeding mechanism moves the specimen through the measurement area. The system supports data storage, display, analysis, output, and printing. The reviewed product source specifies a Chinese-language operating interface.
