Overview
ST-700d is an array Colorimeter developed by 3nh using independent spectroscopic core technology. It adopts built-in large-area silicon photodiode array (double column 40 groups) sensors and industrial-grade MCUs. Strong data processing capabilities ensure the Stability and accuracy of measurement data. Repeatability Delta E * ab is easily controlled within 0.022, and the inter-stage difference Delta E * ab is controlled within 0.2. It can be used for accurate color measurement under various occasions. Large-size touch screen to view measurement results is more convenient. The instrument measurement data is in conformity with other competitors such as Japan, the United States, and Europe. Equipped with three measurement diameters of φ 8mm, φ 4mm and 1x3mm, the adaptability is wider, the measurement Color is accurate, and the performance is stable. It is widely used in plastic electronics, paints Coating, Spinning & weaving printing and dyeing, printing paper products, automobiles, cosmetics and food industries.
