A haze meter measures the light. It quantifies the measure of transmitted light across a material and the degree of scattered and diffused light.

When detecting color differences, the first factors to consider when selecting a light source include its stability, directionality, lifespan, and the effectiveness of the ultimately obtained spectral curve. The illuminant of a colorimeter is a fixed bulb, such as a tungsten lamp，LED light or a long-life xenon lamp. However, for the same color sample, the results displayed by the instrument vary under different light sources. This is because different light sources cause different absorption and reflection of light on the sample, leading to differences in how both the human eye and the instrument perceive the color.

In general, the D65 light source is used in the application of coil steel inks for construction. The D65 light source is equivalent to average daylight. Most coil steel inks for construction are used outdoors, and sunlight is regarded as the standard light source in outdoor environments. For household appliance coil steel inks, due to their usage characteristics, they are mostly used indoors. Therefore, the A standard light source is adopted for color measurement of samples based on indoor lighting conditions. The A light source is a carefully specified tungsten light source. Other light sources, such as fluorescent light sources, can be used in many types of applications. For example, some textile factories use fluorescent light sources. Therefore, a reasonable light source should be selected as the mutually recognized measurement method based on actual usage conditions and user requirements. Once agreed upon by both parties, color measurement must be conducted under the same conditions. This helps reduce unnecessary systematic errors and human errors, achieving the optimal consistency in color measurement.

The 3nh high-precision spectrophotometric colorimeter adopts a combined LED light source with long lifespan and low power consumption, which includes UV (ultraviolet) and UV-excluded options. This design can meet the color difference detection needs of different users and supports the selection of multiple light source modes.

Measurement Accuracy (dE/ΔE): The smaller the value, the higher the match between the color measured by the colorimeter instrument and human visual perception. Generally, dE < 1.0 is regarded as the industrial passing line, while dE < 0.5 falls into the high-precision level.

Measurement Structure: D/8 (integrating sphere structure) is the universal standard, which includes two modes: SCI (Specular Component Included, with specular reflection light) and SCE (Specular Component Excluded, excluding specular reflection light). 45/0 (ring illumination) simulates the human eye's viewing angle and is more suitable for judging reflective materials.

Repeatability: It refers to the difference in color results when measuring the same point multiple times. The equipment can achieve ΔE < 0.08, ensuring highly reliable measurement results.

Illumination Source and Viewing Angle: It is recommended to choose the combination of CIE standard light source D65 (simulating daylight) and a 10° viewing angle.

Application Scenario Requirements: It is necessary to clarify the purchase purpose (quality inspection? R&D? material evaluation?) and the usage environment (laboratory, workshop or field work?).
