Product Description
The YG0922 Handheld Color Spectrophotometer is a state-of-the-art instrument designed for precise color measurement and analysis. With its 45/0 method of illumination and observation, which includes a 45-degree ring-shaped illumination and vertical viewing, it complies with the CIE No.15 and GB/T 3978 standards. The compact integrating sphere size of Φ58mm and combined LED light sources ensure consistent and accurate readings.
This spectrophotometer is equipped with a silicon photodiode array sensor and operates over a wavelength range of 400 to 700nm, with a pitch of 10nm. It covers a broad reflectance range from 0 to 100%, making it suitable for various applications. The measuring aperture is set at Φ8mm, allowing for a focused evaluation of color samples.
The device supports multiple color spaces, including CIE LAB, XYZ, Yxy, LCh, and CIE LUV, offering flexibility in color analysis. It offers various color difference formulas, such as ΔE*ab and ΔE*00, enabling detailed comparison between standard and sample colors. Additional chromaticity data provided by the spectrophotometer include whiteness and yellowness indices, metamerism index, color fastness, and opacity.
For practical usage, it features a 2°/10° observer and supports a wide range of illuminants like D65, A, C, and others. The display data includes spectral value/graph, colorimetric value, and color difference value/graph, offering a comprehensive visualization of results. The measurement time is remarkably quick at just 1.5 seconds, with exceptional repeatability and inter-instrument agreement.
The spectrophotometer is designed with a TFT 3.5-inch capacitive touch screen, facilitating easy operation and data interpretation. Connectively, it uses USB/RS-232 interfaces, and its data memory can store 1000 standards and 10,000 samples, making it ideal for extensive testing needs.
