The 3nh Color Test Chart is a professional color calibration and inspection tool developed by ThreeNH, designed to accurately verify the accuracy and stability of color measurement instruments or assist in data calibration for color management processes.
High-Precision Color Reproduction: Crafted with international standard color card technology, covering multiple standard color gamuts (such as Munsell and Pantone equivalent colors). Color patch values are precisely spectrally calibrated with errors below industry standards (e.g., ΔE≤1.0).
Durable Material: Features a waterproof and scratch-resistant coating, suitable for long-term frequent use in laboratories, production lines, and other scenarios.
As a global leader in image quality testing, we leverage our expertise in image quality testing, equipment, and knowledge to help companies across industries worldwide improve their imaging devices.
Standard camera testing typically covers multiple image quality metrics such as resolution, texture detail retention, noise, dynamic range, color accuracy, distortion, shading non-uniformity, and chromatic aberration. Camera systems often require comprehensive multi-dimensional evaluation.
Through the efforts of our R&D department and the introduction of high-precision production equipment, Threenh has gained the capability to customize various types of test charts. We can produce all kinds of transmission-type test charts (e.g., film charts) and reflection-type test charts according to clients’ specified drawings. Commonly used camera testing charts such as resolution charts, color bar charts, distortion test charts, grayscale charts, and dynamic range test charts can all be customized, significantly reducing costs for high-tech enterprises globally.

FAQs About Test Charts
The repeatability is an important parameter for the accuracy of the colorimeter. Threenh Technology portable colorimeter for color measurements tandard deviation ΔE*ab is within 0.03 (Measurement condition: the average value of 30 measurements on the white board at an interval of 3s after calibration). Each colorimeter can pass the qualified inspection before leaving the factory to ensure it conforms to the standard of China Metrology Institute.
