1. How accurate are these colorimeters?
The repeatability is an important parameter for the accuracy of the colorimeter. These colorimeter standard 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). This repeatability is very excellent among colorimeters at the same price. Each colorimeter can pass the qualified inspection before leaving the factory to ensure it conforms to the standard of China Metrology Institute.
2. Does the digital colorimeter provide a formula for color matching?
These colorimeters provide a color deviation prompt function according to the Lab value, which can provide a reference for color matching. It 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.
3. D/8°and 45°/0°, which one is recommended?
D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries.
4. Can the colorimeter measure light-transmitting materials (such as colored glass and film)?
Since part of the light will pass through the light-transmitting materials, the colorimeter is not suitable for color measurement of such kinds of materials; however, when place a pure color material with uniform texture under the light-transmitting material, we can measure the color difference between the standard and the sample.
5. Can the colorimeter measure powder and liquid?
Opaque liquids and powders can be put into a cuvette for color measurement.
6.Do you offer OEM and ODM service?
Yes. We can supply OEM and make customized design for any specific application.
7. Does the instrument have a warranty?
Guarantee period is 12 months, after the warranty, we also provide life-long paid or service.
8. Do you offer samples to buy?
Yes, you are welcome to order samples to experience our excellent quality and service.
9. Can you offer quality certification?
Yes, we can offer quality certification issued by our lab free of charge, or issued by third-party international inspection
Organizations with extra charge, please contact us for confirmation.
10. Do you have after-sales service?
Yes, our instrument have professional After-sales Dept. lf you have any technical problem or question with our goods welcome to contact us.
