Discontinued:  HAZE Transmission Meter MIZA TrHz-22

THE IMPROVED MODEL is the MIZA TrHz-24

The MIZA TrHz-22 is a Best Value Transmission HAZE Meter in North America and is now upgraded for 2020.This instrument measures either both Haze and Transmittancesimultaneously or one of your choice at a time. The design engineers had simplicity in mind when designing this haze meter. 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 2020 design is sleek and has the latest advancements in optics. The MIZA Transmission HAZE meter TrHz-22 model has a modern compact tabletop minimal design with a repeatability of 0.01 and a new lower price.

Transparencyis a vague description of a material's characteristic of its see-through capability or clearness of the medium, for both liquids and solids. Different 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 their 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. The TrHz-22 haze meter Our instrument measures the latter or wide-angle scattering. Wide-angle scattering occurs at >2.5° from the perpendicular to the material. ASTM D 1003and ISO 13468 measurement methods present different measurements. Note this instrument measures liquid's haze and transmittance 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 better values and have greater repeatability. The MIZA Model TrHz-22 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 MIZA Transmission HAZE TrHz-22 Meter by Imbotec easily measures all translucent materials. These include plastic packaging film, clear PVC, LCD panels, glass, and more.

The TrHz-22 comes standard with a 21mm opening Aperture and a measurement spot of 16.5mm in diameter. Optionally we also have apertures of 10mm, 7mm, and a 5mm aperture for smaller or minimally curved surfaces.

If Clarity is required, check out our TrHz-55.

We also have a model for VERY small objects and for curved or tubular/cylindrical translucent products, "TrHz-77". This haze meter is a specialized model with slit openings of either a 1 or 2mm wide x 21mm long aperture opening. Custom measurement sizes are available upon request. Small apertures are used to measure curved samples like a fluorescent tube as an example.

Transmission Haze Materials Measured

This instrument was designed as a direct response to the Packaging Industry's requirements, thus the TrHz-22 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.

• 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 characteristicsof 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.

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.
