Description
Overview
NS800 are models of spectrophotometer with incomparable accuracy. They feature an ultra-large integrating sphere which can evenly distribute light more effectively, which makes the measurement results more accurate. The errors of the absolute values of L*ab of the spectrophotometers from USA, Germany and Japan are all ±1.5, while, after careful comparison, the error of Lab absolute value of them is only ±1.0.
