First, the spectral characteristics of reflected light are measured by the spectrophotometer, and then the lab value is calculated according to the equation of CIE standard observer function In addition to displaying data in various color spaces, spectrophotometer can also display spectral data directly, providing more detailed information about the color of the object.

3nh also analyzed the parameters of imported spectrophotometer from Japan, the United States and Germany. The absolute value of lab between them was controlled within ± 1.5. The comparison of lab value between ns820 and Japanese instruments, the measurement of any color of goods, can control the gap between lab within ± 1.0, which is the breakthrough of 3nh high-tech, realizing full compatibility with the international market, a high-precision domestic spectrophotometer revolution is coming!

With the rapid development of computer technology, most of the existing colorimeter products at home and abroad use computers to complete the measurement of colorimeter, control box and a large number of data processing work, which makes the operation of colorimeter more simple and fast, the measurement accuracy of colorimeter is higher, and the result is more reliable. These automatic spectrometers can be classified in many ways according to their application requirements, technical specifications or structure. According to the common classification method, it can be divided into visual spectrophotometer with human eye as light detector and automatic spectrophotometer with physical light detector according to the difference of optical detector used.

Features of ns820 spectrophotometer：

1. Beautiful appearance and structure design in accordance with human mechanics;

2. Standard D / 8 ° (diffuse uniform illumination 8 ° receiving) conforms to CIE No.15, GB / T 3978;

3.3.5-inch capacitive touch screen pure screen design interface, friendly operation interface and extraordinary operation experience;

4. Two kinds of standard observer angles, multiple light source modes, multiple color systems, and chromaticity indexes in line with various standards to meet the needs of various customers for color measurement;

5. The repeatability is within Δ e * AB 0.04, and the difference between sets is within Δ e * AB 0.2, with stable test performance;

6. Large capacity storage space, which can store more than 10000 pieces of test data;
