3nh – Optical Instruments for Accurate Color Control

Brand positioning and strategy

Since its founding in 1998, 3nh (Shenzhen Threenh Technology Co., Ltd.) has become a recognized name in color management and optical measurement, operating under the trademark trio of 3nh, Tilo, and Sine Image. The brand strategy emphasizes precision technology (“right time, right place, right people”), offering robust solutions for plastics, textile, printing, cosmetics, food, research, and education sectors. It is one of China's leading manufacturers of color-difference instruments and optical testing technology.

Product Categories – A Deliberately Built System for Color Control

Rather than developing standalone instruments, 3nh has structured its product portfolio as a cohesive system—where each device plays a role in supporting color control at different levels, from visual evaluation to precise data-driven measurement.

Key product categories include:

• Spectrophotometers: Designed for high-accuracy color analysis by measuring reflected or transmitted light across the visible spectrum. Essential in advanced color matching and formulation tasks.

• Colorimeters: Widely used in manufacturing and quality control environments to detect and quantify color differences quickly and efficiently.

• Gloss and Haze Meters: Measure surface gloss and haze to evaluate the appearance of coatings, plastics, printed surfaces, and construction materials.

• Standard Light Booths: Provide stable lighting conditions using standard light sources such as D65, TL84, and D50, enabling consistent visual color assessments across production or QC environments.

Product strengths & industry fit

• High precision and stability: Models like NH310 and NR60CP deliver ΔE deviation within very tight tolerance, rechargeable batteries, and PC-connectable color analysis software.

• Integrated solution approach: combining Tilo light booths and Sine Image charts offers end‑to‑end color control from lighting to measurement.

• Versatility across industries: applicable in plastic extrusion, paint & ink production, textile manufacturing, packaging, cosmetics, food, pharmaceuticals, labs and schools 

Why 3nh stands out in the field of color measurement

What sets 3nh apart is not just product quality, but the way it builds a complete ecosystem for color control. From colorimeters, spectrophotometers, gloss meters to standard light booths and image test charts – each tool is designed to work in sync, ensuring accurate and consistent results throughout the workflow.

Its ability to adapt across different industries – from manufacturing to lab testing – makes 3nh a reliable partner in sectors where color precision is critical, such as printing, packaging, plastics, textiles, and cosmetics.

More than instruments – a foundation for color consistency

3nh offers more than just measuring tools. It provides a complete solution that helps users standardize and control color quality from input to final product. By integrating precise devices with controlled lighting and image analysis tools, 3nh enables consistent color management at every stage of the production chain.
