sechayi.com.cn is a vertical industry website for colorimeters owned by Shenzhen 3nh Technology (formerly 3nh Color Technology), a domestic manufacturer of color detection equipment. Its core business is selling self-branded 3nh domestic colorimeters, while also acting as an agent for multiple imported colorimeter brands. It offers second-hand colorimeter trading, maintenance and calibration services for all colorimeter brands, and also provides popular science content on colorimeter use. It is a B2B instrument sales and service site targeting industrial customers.
The site's product range covers all categories including spectrophotometric colorimeters, benchtop colorimeters, and handheld colorimeters. Its in-house domestic colorimeters span from entry-level to high-precision industrial models. The representative KS series meets industrial-grade accuracy standards, with a repeatability ΔEab as low as 0.025. It supports multiple aperture adapters for samples of different forms, and offers cross-platform data collaborative management across mobile phones, computers, and WeChat mini programs. The site also carries imported colorimeter products from brands including X-Rite and Konica Minolta, and provides cost-effective maintenance and calibration services for out-of-warranty imported colorimeters. In addition, the site publishes a large amount of educational content on colorimeter selection and troubleshooting, to help new users get up to speed quickly.
Advantages: 3nh has over 20 years of industry experience and is a leading manufacturer in China's color detection field. Its in-house domestic colorimeters are priced much lower than imported options, offering outstanding cost performance. It also has regional offices across China, enabling fast offline after-sales response, and can meet one-stop full-process needs for procurement and maintenance.
Disadvantages: The site has an outdated design with a lot of duplicated, redundant content that leads to a poor browsing experience. On top of that, product prices are not listed publicly — users have to call customer service to inquire, which makes the shopping process much less efficient.
This site is suitable for domestic manufacturing enterprises in need of colorimeters, including plastics, printing, textile, and ceramics production, as well as laboratories and quality inspection departments that need colorimeter maintenance and calibration. It is directly accessible within mainland China.
