MIZA TrHz-55 Clarity, Haze, Transmittance & Spectrophotometer Professional Model

The MIZA TrHz-55 Clarity, Haze, Transmittance & Spectrophotometer "Color" instrument is a transmission-based haze instrument that measures both solids and liquids using a spectrometer sensor for higher accuracy measurements. The TrHz-55 is an advanced unit for laboratories that want to have an efficient instrument doing a variety of measurements using reduced table space.

The MIZA TrHz-55 Transmission HAZE Meter model comes with the industry's best three-year warranty.  This instrument was designed for both vertical and horizontal positions. The design is sleek and has the latest advancements in optics for high precision. 

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-55 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.

The TrHz-55 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.

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.


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.
