FAQs About  ISO Test Charts

To extend the life of a haze meter, keep the instrument dust-free and clean, regularly calibrate it, and control for a stable dry storage. For better results, avoid letting the optics dry, and leave the meters under sunlight. For optimal performance, have the meter professionally serviced once a year.

The Ideal Accurate and User - Friendly Spectrophotometer for Your Needs 

This Spectrophotometer device measures the reflectivity，absorbance, transmittance, and fluorescence of light passing through samples, providing invaluable data for a wide range of applications, provide unrivaled accuracy for reliable results. 

Selecting an appropriate spectrophotometer offers significant advantages for precision color analysis and quality control. When choosing an accurate and user - friendly spectrophotometer, consider factors such as wavelength range, sensitivity, sample handling options, and available software features. By investing in the right spectrophotometer, you can streamline your analytical processes, obtain more accurate results, and enhance the overall efficiency of your laboratory or industrial operations. 

 Choosing the right model—whether portable, benchtop, or inline—aligns technology with specific industry needs, ensuring long-term reliability and optimized color management.

In industrial production and quality control, color consistency is one of the core elements determining product quality. Whether it is the metallic paint for automobile coating, the dyeing effect of textile fabrics, or the ink matching in packaging and printing, subtle color deviations may lead to cost waste or damage to brand image.

The LAB color space defines colors with a three-dimensional model:

  1. Lightness (L): It indicates the lightness or darkness of a color, ranging from 0 (pure black) to 100 (pure white).

  2. Hue and Saturation (a and b):

    • The a-axis represents the red-green tendency, with positive values leaning towards red and negative values leaning towards green;

    • The b-axis represents the yellow-blue tendency, with positive values leaning towards yellow and negative values leaning towards blue.

It is a globally recognized standard and supported by most modern color measurement equipment. Color is quantitatively analyzed by measuring Lab values with instruments.


The repeatability is an important parameter for the accuracy of the colorimeter. Threenh Technology portable colorimeter for color measurements tandard deviation ΔE*ab is within 0.03 (Measurement condition: the average value of 30 measurements on the white board at an interval of 3s after calibration). Each colorimeter can pass the qualified inspection before leaving the factory to ensure it conforms to the standard of China Metrology Institute.

To determine haze, haze meters are used in multiple industries such as plastic, glass, film, coating, and displays. This ensures that all optical quality of the product is in the appropriate specification, including aesthetic compliance and meeting the intercontinental quality standards.
