For complete color evaluation, the CAC is commonly outfitted with D65 (daylight), TL84 (store light), F (home light), UV, and CWF (cool white fluorescent) lamps. 

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 five common gloss levels are:

1. Flat/Matte (0–10 GU)

2. Eggshell (10–25 GU)

3. Satin (26–40 GU)

4. Semi-gloss (41–70 GU)

High Gloss (71–100+ GU)
These levels vary slightly depending on industry and standards used.

Spectrophotometers can only measure haze if it has haze measuring capabilities, as many measure color and transmittance.

Light booths and color matching are essential for the textiles, printing, automotive, plastics, cosmetics, and coatings industries. These fields rely on tight color alignment to protect brand value and meet global quality demands for color. 

Set the 3nh booth in a tidy, stable position with neutral, clean surroundings, adequate airflow, and a reliable power source, and position it away from direct sunlight or mirrors. 

The most important equation is A = 2εcl, where A is the absorbance, 2 is a constant, ε is the molar absorptivity (L/mol cm), c is the concentration (molL-11), and l is the path length (cm). This can be used to relate the absorbance to the concentration, allowing quantification through colorimetric assays.

Haze Meters are utilized in production and quality assurance in the plastics, glass, films, and coatings industries, where transparency and example are essential.

At most of time, we have stock in the factory. Generally it is 1-3 working days after the payment confirmed. After shipped, we will email you the tracking number. You can check the shipping status of your order on the website. If you are in urgent need, we can consider making special arrangement for you.

Follow the calibration steps form 3nh. Don’t touch the sample and drop the measurement light to eliminate external light.
