NS808 Yxy Brightness Value Spectrophotometer for road line paints with SQCT software
NS808 is a model of spectrophotometer with incomparable accuracy. It features the great performance in the measurements of traffic signs with the help of dedicated PC software CQCT and a 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 L*ab absolute value of our NS series spectrophotometer is only ±1.0.
It is configured with two observer angles, multiple light source types, multiple color space systems and color difference formulas, all of which have endowed NS series spectrophotometer with powerful functions to meet the requests of all kinds of color measurements.
The large touch-screen display makes operation more friendly. And once connected with PC via the software CQCT, more extension functions will be at hand.
Features:
1. Specially designed to measure traffic signs.
2. Elegant appearance combines ergonomic design
3. 45°/0 geometry optical structure, conform to standard CIE, ISO, ASTM and DIN, incomparable accuracy.
4. 3.5" ultra-large touch-screen makes the operation interface quite friendly.
5. Two kinds of standard observer angles, multiple light sources, multiple color spaces and multiple color difference formulas, fit for all kinds of color measurement requests.
6. Repeatibility ΔE*ab within 0.04, inter-instrument ΔE*ab less than 0.2, super stable and reliable performance.
7. Large capacity storage, more than 15000 data.
8. PC SQCT software with powerful extension functions.
9. High hardware configuration with a number of innovative technologies.
