The automotive, aerospace, metal finishing, marine, construction, and manufacturing industries utilize and rely on coating thickness gauges the most. They ensure that coatings are within the expected criteria for functionality, safety, and durability.

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.

Different types of substrates require different kinds of digital gauges. Magnetic gauges are for ferrous metals, eddy current gauges are for non-ferrous metals and ultrasonic gauges are for any non-metal composites like plastics. Careful selection of a gauge is the most important factor for obtaining accurate measurements.  

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. 

Colorimetry is a method that applies color intensity to ascertain the chemical concentrations. It is founded on Beer-Lambert Law, whereby the absorbance at a given wavelength is proportional to the concentration. It is popular in environmental and biochemical testing.

The LAB color space defines colors in a three-dimensional model: Lightness (L), red–green axis (a), and blue–yellow axis (b). It's a globally recognized standard supported by most modern color measuring devices. CIELAB is a standardized, device-independent system designed to map all visible colors that the human eye can perceive.

The LAB color space uses three values to define any color, each representing a specific dimension:

L (Lightness): Ranges from 0 to 100. It measures the brightness of the color, where 0 is pure black and 100 is pure white.
A (Red-Green Axis): Ranges from approximately -96 to +127. Positive values represent red tones, while negative values represent green tones.
B (Yellow-Blue Axis): Ranges from approximately -96 to +127. Positive values represent yellow tones, while negative values represent blue tones.

Record the L*a*b values of the sample and the reference with a calibrated spectrophotometer or colorimeter. Compute the difference in the color by use of ΔE. The lower the Delta E, the more accurate the result. The difference in energy, ΔE < 1, is generally assumed to be invisible to the eye.

When using a Pantone light box, each sample should be positioned flat and nearby the other samples, but not overlapping. Each one should also be in the middle of the light box, and the surfaces of the light box should be clean and non-reflective.
