Product Introduction

1. Product Introduction:

The NJ-808S colorimeter/spectrophotometer is developed and produced by Beijing Naijiu Weiye Technology Co., Ltd. It is suitable for measuring the chromatic coordinates of retroreflective materials such as road signs, markings, protruding road signs, contour signs, etc. in traffic engineering. The instrument is compact and exquisite, adapting to relevant standards and specifications of traffic engineering.

2. Functional features:

1. 45 ° circular illumination, 0 ° observation angle. Innovative circular lighting system that eliminates directional dependence and reduces the impact of patterns

Lowering to the lowest level. Measurement on frosted, textured, and structured material surfaces brings great advantages

2. Used for measuring the brightness factor and chromaticity coordinates of traffic signs, markings, and reflective films, including GB 2893 "Safety Colors" and GB/T 18833 "Road Traffic Reflective Films" standards.

3. Excellent repeatability and inter station difference: repeatability Δ E * ab ≤ 0.02, inter station difference ≤ 0.25

4. Intelligent automatic calibration, with a reference of ZrO2 with a reflectance greater than 90%, eliminating the need for frequent whiteboard calibration of 10nm resolution grating spectroscopy technology

5. Provide 30+measurement parameters and 37 evaluation light sources

6. Supports Android, IOS, and Windows programs
