Transparency of a product is influenced by the absorption and scattering behavior of the specimen. Visually transparency is described by two phenomena: Haze and Clarity. The haze-gard i haze meter measures all transparency parameters in one instrument: total transmission, haze and clarity. Additionally, it simultaneously displays the results according to the ASTM and ISO standard test methods. The outstanding precision and reliability of the haze-gard i, as well as its ease of use, have made the haze meter the standard for transparency measurement in the glass, plastic, film and packaging industries.
