Product Description

CS-821N

CS-821N is a highly stable benchtop spectrophotometer; the newly upgraded auto-calibration technology ensures excellent stability of the instrument for long-term use and measurement, even in the case of drastic environmental changes. Benchtop spectrophotometer cs-821N has two illumination sources: pulsed xenon lamp and led; with 24 standard light sources and 40+ measurement indicators, it can simulate and calculate color data under various light sources and color indicators.

       ·Automatic calibration

　　·Excellent long-term stability

　　·It has two kinds of lighting sources: pulse xenon lamp and led

　　·Support SCI + SCE simultaneous rapid measurement

　　·Short term repeatability:Δ E * AB ≤ 0.015

　　·Long term repeatability: Δ E * AB ≤ 0.015
