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.

A magnetic induction gauge measures galvanized coatings by sensing the zinc coating on steel and iron. The measurement tells how thick the protective coating is. This is done to ensure the prevention of rusting.  

Techniques of measuring color are visual color comparison, colorimetry (with colorimeters) and spectrophotometry (measuring spectral reflectance), and image analysis. Both techniques measure the reflection or absorption of light by materials and are commonly quantified. Therefore standardized in color spaces such as CIELAB or RGB.

The CCC is much like the CAC yet it frequently has advanced programmable lighting, sophisticated electronic control systems that allow for light source switching, and advanced visual testing.

To keep a neutral background, helping to reduce color distortion and bias.

To determine haze, haze meters are used in multiple industries such as plastic, glass, film, coating, and displays. This ensures that all optical quality of the product is in the appropriate specification, including aesthetic compliance and meeting the intercontinental quality standards.

There are many factors that can influence accuracy such as surface roughness, temperature, substrate material, and calibration settings. For ferrous metals, external magnetic fields can also distort measurements. Proper calibration and preparation will help reduce the impact of these factors.

The gloss of the paint is defined by the measurement of light reflection at the surface of the paint with the help of a gloss meter. The angle and quantity of light reflected determine the level of gloss, with smoother and reflective surfaces having a higher level of gloss.

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

True color in chemistry is the color seen in a solution or compound in standardized conditions. It depends on electronic transitions in molecules, specifically absorption of a particular wavelength of light, and this depends on the structure of the compound.
