A coating thickness gauge measures coating thickness. It measures coating thickness using three different principles: magnetic induction, eddy current, or ultrasonic. Depending on the coating type and the coating's substrate material, the appropriate principle is selected. For industrial and laboratory use, most of these units deliver accurate, non-invasive readings.

The color measurement theory is the quantification of the interaction of materials with light, either absorption, transmission, or reflection. It employs standard colour spaces (such as CIELAB) and devices (colorimeters, spectrophotometers) to code the visual colour into objective and reproducible data.

Haze captures the scattering of light, transmittance measures the light that passes through a said material.

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:

1. Lightness (L): It indicates the lightness or darkness of a color, ranging from 0 (pure black) to 100 (pure white).

2. 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.

1. Turn on the hazemeter and check if the instrument’s display screen shows normally and if the buttons are responsive.

2. Verify that the hazemeter’s battery power is sufficient. Replace the battery or connect an external power supply if necessary.

3.  Confirm that the instrument’s measurement mode is set correctly. Select the appropriate measurement unit and range based on actual needs.

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.

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.

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. 

Replace when the total hours exceed rated life, decrease in brightness, or the color temperature shifts beyond tolerance.
