Overview
ST-700d Plus is an array Colorimeter developed by 3nh using independent spectroscopic core technology. It adopts built-in large-area silicon photodiode array (dual-row 40 groups) sensors and industrial-grade MCUs. Its powerful data processing capabilities ensure the Stability and accuracy of measurement data. The instrument Repeatability Delta E * ab is controlled within 0.02, and the inter-stage difference Delta E * ab is controlled within 0.18. It can be used for accurate color measurement under various conditions. Equipped with five measurement diameters, the adaptability is wider. It is widely used in plastic electronics, paints Coating, Spinning & weaving printing and dyeing, printing paper products, automobiles, cosmetics and food industries, as well as scientific research institutions and laboratories.

Principle
The ST-700d Plus uses D/8 illumination mode (diffuse illumination, 8 ° direction reception) to support SCI/SCE measurement, including UV/exclusion UV measurement. The instrument uses planar grating spectroscopy technology to illuminate the sample by combining a full-light spectrum LED light source and a UV light source. The reflected light signal is received by a large-area silicon photodiode array sensor, and the spectroscopic measurement is performed at 10nm intervals in the wavelength range of 360~ 780nm. Finally, various Color parameters are calculated.
