TrHz-33 MIZA Transmission HAZE Meter  "Mid-Advanced Model"

The TrHz-33 Transmission HAZE Meter Mid-Advanced model with a two year warranty was designed with superior accuracy and simplicity in mind. This instrument was meant for a discerning audience who require a better than entry-level instrument yet has more value than the older traditional instruments costing twice as much. The accuracy and repeatability specifications rival the more expensive designs from Germany. This instrument was designed for both vertical and horizontal positions. The 2017 design is sleek and has the latest advancements in optics. Thus, the MIZA Transmission HAZE meter TrHz-33 model was born.

“Transparency” is a vague description of the material characteristic. Products require different solutions. Packaging for a meat product in a grocery store should be extra clear or transparent, while plastic bags are semi-opaque to keep its contents private. Transparency involves the combination of reflection, transmission, and absorption of the translucent material. Another characteristic also visible to the human eye is the haziness or cloudiness of a material. Haziness or HAZE can be characterized by the scattering of light. Scattering is also divided into Narrow and wide-angle scattering. Our instrument measures the latter or wide angle scattering. Wide-angle scattering occurs at >2.5° from the perpendicular to the material. ASTM D 1003 and ISO 13468 measurement methods present different measurements. 

ASTM D 1003 uses illuminants A and C while ISO 13468 uses Illuminant D65.

Our Imbotec MIZA Transmission HAZE Meter easily measures all translucent materials. These include plastic packaging film, clear PVC, LCD panels, glass and more.

Materials Measured

This instrument was designed as a direct response to the Packaging Industry’s requirements, thus Novo-Haze TX was developed to measure films and thin sheet products.

  • Plastic film
  • Acetate
  • Polyester film
  • Mylar
  • Vinyl film
  • Glass (Thin)
  • Colored film
  • Dark film

What is Transmission Haze?

Transmission Haze is 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 optical characteristics of plastics and packaging films.

Meat with hazy packaging

 In packaging applications hazy films may reduce a consumer’s quality perception as packed products with haze affected films 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.
