The JKOA-9325 spectrophotometer provides over 30 measurement parameters, including spectral reflectance, CIE-Lab, E-LCh, ΔE*ab, hiding power, whiteness, yellowness, etc.; and offers nearly 40 evaluation light sources to choose from, such asA, B, C, D50, D55, D65, covering almost all color measurement parameters and light source types in the industry.




JKOA-9325 Spectrophotometer
--------Ultra-high repeatability accuracy: dE*ab≤0.03

Core Technologies
(1) Dual-Optical Path Design Improves Repeatability Precisio to dE*ab ≤ 0.03
The dual-optical path design monitors light source energy fluctuations while measuring sample signals, reducing interference during measurement to achieve higher measurement stability. This improves the measurement repeatability to dE*ab ≤ 0.03, ensuring high standards for measurement speed, accuracy, stability, and inter-instrument consistency.
(2 Innovative 5-Micron Thick Nano-Integrated Optical Components
Adopting nano-integrated optical components as the spectrometer, a thickness of only 5 microns achievale spectral resolution, greatly enhancing the product's technical performance.
(3) Ultra-High Repeatability Precision: dE*ab ≤ 0.epeatability precision is a key indicator of a spectrophotometer's accuracy. The JKOA-9325 spectrophotometer employs rigorous standards for repeatability evaluation, d outstanding repeatability performance.
(4) Excellent Inter-Instrument Consistency
Superior technology and craftsmanship ensure the JKOA-9325 possesses excellent inter-instrument tency. Using BCRA series standard tiles for color transfer and value traceability guarantees the instrument's superior inter-instrument difference level.
(5) Calibration Base and Zirconium Standrd with Mohs Hardness 9 Ensure Long-Term Instrument Stability
Compared to existing products, the JKOA-9325 spectrophotometer does not require frequent manual calibrn during use. Simply place it on the calibration base, and the instrument will automatically calibrate its overall functionality and accuracy based on its internal status and environmental factors, ensuring the instrument remainle and ready for use at all times.
The white tile in the calibration base is the foundation of the instrument's operation. It integrates zirconium material, known as "artificidiamond," as the calibration white tile, with a surface Mohs hardness of 9. Due to the material's diamond-like hardness and stability, the calibration tile surface is scratch-resistant ill not discolor with changes in temperature and humidity. Compared to similar domestic and foreign products that use ordinary industrial ceramics or even plastic for calibration tiles, this further improves stability and durability, e instrument's performance.
