Ambient light may affect the test results and must therefore be kept to a low level for accurate haze meter results. 

The gloss meter is used to measure gloss at typical angles (typically 20°, 60°, or 85°). The instrument illuminates the material and measures the amount of light reflected and states the outcome in gloss units (GU), which is related to perceived brilliance.

This refers to assessing samples with a specific color and maintaining the same alloted time interval on all parameters to ensure neutrality of variables and reproducibility of lightness in the color. 

To take care of a haze meter to make it last longer, ensure that it is cleaned, recalibrated regularly, and stored in a dry, dust-free place.

Colors look different under various lights mainly because of metamerism—a phenomenon where two colors that match under one light source fail to match under another, caused by differences in the spectral composition of light.

Different lighting varies the color perception of objects. Warm light, like that from incandescent bulbs, tends to make colors more yellow, while daylight presents a bluish tint. Our color vision system plays a compensating role using a mechanism called color constancy.

Every light source emits light with a unique "spectral fingerprint" (i.e., the range and intensity of wavelengths it contains). This directly affects how an object’s surface reflects light and how our eyes perceive its color.

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.  

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.

An inappropriate viewing angle may lead to reflections or color shifts in the light. The correct angle of 45 or 0 will provide the real color of the assessment without the distraction of glare.
