Depending on model and location, delivery time is usually 2-4 weeks for standard models and 4-6 weeks for built- to-order ones. 


A powder coated surface is most commonly measured for thickness post curing using a digital coating thickness gauge. This method is non-destructive, helps verify coverage uniformity and meets quality control standards. A powder comb gauge is used to estimate thickness for a pre-cured coating.

The ΔE (Delta E) formula of the CIELAB color space is usually used to measure color difference. The difference is measured in a colorimeter or spectrophotometer to gauge the level of perceptibility of the difference between two samples in terms of L*a*b*.


Make sure the light sources are calibrated, keep extraneous light sources away, have the correct viewing angles, and handle the samples in a clean and uniform manner.


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.


A CAC is a professional light booth designed to provide standardized lighting conditions for visual color assessment. It includes multiple light sources like D65, TL84, and UV.


A colorimeter is a scientific instrument used to measure and analyze the color characteristics of objects or materials. It quantifies color by evaluating specific parameters related to human visual perception and standardized color spaces.
