Transmission Hazemeter
Article number:
The Novo-Haze TX Transmission Hazemeter offers fast and accurate measurement of the optical quality of plastic films and other transparent materials.
ASTM D1003 Standard Test Method for Haze and Luminous Transmittance of Transparent Plastics.
In packaging applications hazy films may reduce a consumer’s quality perception as packed products can look cloudy and indistinct. For plastics with haze the visibility of the test material becomes more apparent and the contrast of viewed objects is reduced.

Features
The Novo-Haze TX transmission hazemeter quantifies the optical qualities of transparent materials. The two most important aspects are:
1. Transmission — a measurement of the total amount of light that passes through a material that is influenced by absorption and reflective properties.
In the plastic film industry, the transmission measurement is related to the opacity of the material and/or the hiding power of the applied coatings.
2. Transmission Haze — a measurement of the light scattering characteristics of a material. Haze can be due to suspended particles or contaminants within a sample or fine surface texture & contamination.
Haze measurement can be used to quantify the optical characteristics of plastics and packaging films.
