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.

The most common standard measuring gloss is ASTM D523, which covers the procedures of using a gloss meter at 20°, 60°, and 85° angles. The other international standard that is widely used in industrial and laboratory applications is the ISO 2813.

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.

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.

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. 

The number of reflected light is a measure assigned by a gloss meter as a gloss unit (GU). It is a normalized quantity in which 100 GU is normally a perfect reflection at 60°, and 0° GU is a full diffusion.

Look for dirty or fingerprinted glass along the optical path, recalibrate with standards, and check the set-up for outside light so that it is controlled. If the problems still exist, please reach out to the helpdesk or book a service with your professional service.

They provide accurate and repeatable assessments of color in various settings for the purpose of avoiding inconsistencies in mismatched items and ensuring steady production or branding.

A calorimeter is used to measure heat that is gained or lost during a chemical or physical reaction. A sample is taken in an insulated container, and a temperature change is measured. This assists in computing the alterations in energy by the equation Q = mcΔT, where Q is heat.

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.
