At most of time, we have Spectrophotometer 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.
Ambient light, heat, and moisture levels should be regulated. The use of colored walls and reflective surfaces should be avoided, as they can damage the assessment of the sample colors visually.
Of course! Many portable, battery operated, and lightweight coating thickness gauges are available for on-site and field inspections. They provide quick and accurate results and portable gauges are ideal for construction, automotive, and industrial environments.
A light booth for color matching usually contains D65 (daylight), TL84 (store), A (incandescent) and UV light. LED may also be used in modern time for additional color matching.
If there is uneven lighting, color shifts, and the light is not as bright as it was before, your lamps might have to be replaced. Recent light boxes used with Pantone, as well as Datacolor LightBooths, have usage timers that tell how long before a lamp needs to be replaced.
Each haze test can take from 3 to 10 seconds depending on the device and the type of sample.
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:
Lightness (L): It indicates the lightness or darkness of a color, ranging from 0 (pure black) to 100 (pure white).
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.
Compared to an analog model, digital gauges not only provide more accuracy, but also allow for greater repeatability and are easier to work with. Advanced digital gauges allow for features such as data storage and automatic calibration and statistical analysis. For these reasons, digital gauges are the preferred choice for professional applications.
For a proper color evaluation, ensure cleanliness, use standardized observation conditions, eliminate stray light, and periodically change the lamps.
A colorimeter or spectrophotometer should be used to measure the color of a solution. The instrument directs light through the liquid and quantifies absorbance at certain wavelengths. The values obtained indicate the color intensity of the solution and, by default, the concentration of the solution.
