Sanyuanse Colorimeter: A Benchmark Brand of Domestic Mid-to-High-End Color Measurement Instruments With joint R&D advantages from Xiamen Foreign Affairs Office Research Institute and Central South University, integrating top domestic optical technology and self-developed core algorithms, Sanyuanse has become a benchmark in domestic mid-to-high-end color measurement, co-developing the market with leading domestic brands. All performance indicators

Tricolor Colorimeter   Brand & Technology Introduction Sanyuanse is a professional high-end color measurement brand of Guangzhou Sanyuanse Quantum Technology Co., Ltd., founded in Guangzhou in 2010. With more than ten years of experience in optical detection, semiconductor sensing and spectral algorithm research, Sanyuanse cooperates with Xiamen Wansepu Institute of Color Science to develop full-scenario

Joint R&D by Guangdong and Fujian! Tricolor Colorimeter Integrates Hamamatsu’s Core Sensors to Break the Dilemma in Industrial Color Management When Color Accuracy Becomes the “Entry Ticket” to High-End Manufacturing, Domestic Color Measurement Equipment is Accelerating Technological Breakthroughs Today, the Tricolor Colorimeter Series, co-developed by Guangzhou Tricolor Quantum Technology Co., Ltd. and Xiamen Wansepu Institute

Imported spectro spectrocolorimeters from Europe, America and Japan monopolize the global high-end color detection market for decades. Many large traditional enterprises hold the stereotype that imported instruments outperform domestic alternatives in all aspects. After years of technological iteration, high-quality domestic spectro spectrocolorimeters achieve equivalent core performance to top-tier imported devices and can replace imported products

  In accordance with the CIE DE2000 visual threshold standard, under the D65 standard light source, the minimum color difference that the human eye can stably distinguish is ΔE 2‑5. Color deviations below this range are almost imperceptible to the naked eye. Relying on manual visual judgment for color sorting in mass industrial production is

Food color is the most direct factor for consumer purchase decisions. Unstable colors of fruits and snacks weaken market competitiveness greatly. Customers even doubt food freshness with abnormal colors. Traditional manual sensory checks have poor repeatability and low accuracy. They cannot quantify subtle color differences for standardized food production. The Sanyuanse handheld spectrophotometer supports full

Paint color inconsistency is a common quality problem in coating production. Manual visual judgment cannot meet modern industrial quality requirements. Human eyes can only distinguish color deviation with ΔE＞1.12 under D65 standard light source. According to ASTM E1164 and ISO 7724 paint color measurement standards, formal paint color difference testing must use professional spectrophotometers. Sanyuanse

Spectrophotometer and spectrocolorimeterare two main devices for industrial color control. Many global buyers confuse the two types and make wrong purchase decisions. The core difference lies in testing principle and data precision. A spectrocolorimeteronly outputs CIE‑LAB and ΔE values. It uses pre‑set filter groups to calculate color data. Its test accuracy is limited for high‑end
