To use a haze meter, the device must first be calibrated and then it will display the haziness and transmittance values.

Threenh Technology colorimeters provide a color deviation prompt function according to the Lab value, which can provide a reference for color matching. The handheld colorimeter can only indicate blacker, whiter, redder, greener, yellower or bluer, but it cannot provide accurate color formulas. Only with the help of a spectrophotometer and professional color matching software can fully realized automated color matching.

A colorimeter is used to measure absorbance at selected wavelengths with the help of filters, which is suitable for rapid comparison of colors. A more advanced spectrophotometer has a monochromator. It can measure a larger range of the spectrum of light and is more accurate. You can also get detailed color data at visible and non-visible wavelengths.

Color evaluation will change based on how a sample is viewed.  A 45° viewing angle to the source is recommended to reduce shading and achieve consistent comparison.

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.

To quantify color change, take the original L*a*b* values of a sample, and reread after exposure or processing. Compute the difference as 1/2(Emut1 Emut2). The larger the value of ΔE, the more obvious the change of color is, which can be used in quality or stability testing.

Yes. We can supply OEM and make customized design for any specific application. Our MOQ for OEM and ODM service is 5 pcs for one model. We can not only offer standard machines, but also customized machines. Don’t hesitate to tell us your requirement, we will try our best to meet your needs.

The color measurement test applies a colorimeter or spectrophotometer to evaluate the way a sample reflects or absorbs light. It is given in objective color values (L*a*b*, RGB, or absorbance) and is usually contrasted to a standard in quality control or compliance.

An 18% gray background reduces distractions and color bias, helping in a more accurate assessment.

1. Turn on the hazemeter and check if the instrument’s display screen shows normally and if the buttons are responsive.

2. Verify that the hazemeter’s battery power is sufficient. Replace the battery or connect an external power supply if necessary.

3.  Confirm that the instrument’s measurement mode is set correctly. Select the appropriate measurement unit and range based on actual needs.
