HAZE Transmission Meter



MIZA TrHz-24


The MIZA TrHz-24 is the Best Value 2021Transmission HAZE Meter in North America. The MIZA TrHz-24 is a new upgraded model for 2021.  The TrHz-24 replaces the successful TrHz-22.

This instrument measures either both Haze and Transmittance simultaneously or just one at a time. The TrHz-24 is our Improved 2020 Version. The design had simplicity in mind. This instrument is meant for customers searching for an accurate, repeatable yet affordable priced instrument that rivals and exceeds the performance of older traditional instruments costing three times as much. Note that the accuracy and repeatability specifications exceed the more expensive older designs. This slim instrument was designed in the vertical position requiring much less tabletop real estate than horizontal style units. The 2019 design is sleek and has the latest advancements in optics. The MIZA Transmission HAZE meter TrHz-24 model has a modern compact tabletop minimal design with a repeatability of 0.01 and lower price.

Transparency” is a vague description of a material characteristic, whether a liquid or a sold. 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. Note this instrument does not measure liquids in a horizontal position. 

ASTM D1003 refers to two test procedures that cover the evaluation of specific light-transmitting and wide-angle scattering properties. The two test methods under ASTM are Test Method A and B. Test Method A uses a Haze meter while Test Method B uses a spectrophotometer. The better and more accurate test method is A which uses a Haze Meter. These results offer slightly higher value and have greater repeatability. Our MIZA Model TrHz-24 uses the total hemispherical luminous transmittance. This is accomplished by placing the planar product against the entrance port of the sphere which we call the "Haze Port"

Quality Control personnel use these Haze meters to standardize the quality of a product for specification purposes.

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

Our Imbotec MIZA Transmission HAZE TrHz-24 Meter easily measures all translucent materials. These include plastic packaging film, clear PVC, LCD panels, glass and more.

The TrHz-24 comes standard with a 21mm opening Aperture and a measurement spot of 16.5mm in diameter. Optionally we also have measurement spots of 10mm, 7mm, and a 5mm aperture. 

We also have a model for very small objects and for curved or tubular translucent products, "TrHz-77". This haze meter is a specialized model with slit openings of 1 or 2mm wide x 21mm long aperture openings.  Custom measurement sizes available upon request. The small aperture can measure a curved sample.

Materials Measured


This instrument was designed as a direct response to the Packaging Industry’s requirements, thus the TrHz-24 was developed to measure films and thin sheet products quickly and easily (Use our Thin Film Sample Holder TrHz-96). Just lay the sample on our aperture ring and place the larger ring over it to create a taught firm sample on the measurement surface and press the measurement button.

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 is measured in percent. Haze is calculated by dividing the Diffuse Transmission by the Total Transmission in percentage. Normally CIE Illuminant C is used for these calculations.

Haze measurement can be used to quantify the optical characteristics of plastics and packaging films.

   haze film sample


In packaging applications hazy films may reduce a consumer’s quality perception as packaged 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.
