High-Definition Camera for Precise measuring Area Positioning
The display provides ultra-clear imagery of the areas to be measured, enabling operators to quickly and intuitively select measurement zones. This precision reduces measurement errors and enhances overall measuring productivity.
Dual Optical Path Spectral Analysis Ensures Outstanding Accuracy and Stability
The dual optical path design tracks changes in light source energy while it measures samples, reducing measurement errors. This improves the instrument’s stability and precision, achieving a repeatability of dE*ab ≤ 0.02. It delivers consistently fast, accurate, and stable results. The technology is patented in both China and the U.S.
More advantages
Supports Both Reflectance and Transmittance Measurements: Features a D/8 geometry for reflectance (integrating sphere with diffused illumination and an 8-degree observation angle) and a D/0 geometry for transmittance (integrating sphere with diffused illumination and a 0-degree observation angle), enabling precise liquid measurements of APHA, Pt-Co (Platinum-Cobalt Index), and Gardner (Gardner Index).
Damping Mechanism in Measuring Handle and Clamp:The measuring handle is designed with a damping feature that allows it to rebound slowly and naturally, reducing the risk of damaging the samples. Similarly, the clamp used for reflective measurements also has a damping mechanism. This ensures a gentle rebound that protects the samples while securely holding them in place.
Compatible with SCI/SCE Measurements:Utilizes the D/8 illumination conditions recommended by the International Commission on Illumination, fulfilling the requirements across various industries; enables simultaneous measurements with specular component included (SCI) and specular component excluded (SCE), offering more comprehensive insights into color data changes.
Four Measurement Sizes: Offers four sizes of measurement openings, with the biggest being an inch wide, making it easier to measure a variety of sample sizes.
