Transmission haze meter with close tolerance

Article No. 4797

haze-gard i Pro
Haze meter for crystal clear glass with toughest limits

Complete transparency control by taking only one reading:

Total transmittance
Transmission haze
Clarity

Improved performance for very low Haze levels < 0.3%

Measurement stability guaranteed with automatic measurement mode and additional calibration / verification at Haze < 0.3 %

Features

Transparency of a product is influenced by the absorption and scattering behavior of the specimen. Visually transparency is described by two phenomena: Haze and Clarity. The outstanding precision and reliability of the haze-gard i, as well as its ease of use, have made the haze meter the standard for transparency measurement in the glass, plastic, film and packaging industries.

Optimized for Haze levels < 0.3 % with close tolerance
Repeatability for Haze (ASTMillum. C) < 0.3 %: 10% of measured value or > 0.01 units
Simultaneous measurement of haze and transmission according to
- ASTM D1003 – illuminants C and A (non-compensated method)
- ISO 13468 – illuminant D65 (compensation method)
Open measurement compartment – quickly change and position small and large samples
Reference beam, self-diagnosis and enclosed optics ensure precise and reliable readings - any time
Automatic and long-term calibration allow easy and fast operation of the haze meter
10 year warranty on LED light source – long-term stable results for many years
Versatile sample holders for films and sheets available
Horizontal or vertical set-up - convenient sample handling for any application
Foot switch for hands-free operation
Large color touch display with symbols to select menu functions

A comprehensive guide to Abrasion Resistance

We are confronted with abrasion resistance every day. Whether it is your shiny new bathroom floor that is beginning to fade or a scratch on the case of your new phone or car. Abrasion can ruin a day in a moment. So how do we test and improve our coatings on these appliances to mitigate the chance of this happening? In this article we will discuss what abrasion resistance is, how it relates to other physical properties, and what tools and methods are needed to measure it.

Transparency Measurement

To guarantee consistent and uniform products, transparency measurement is a need. Depending on the application, the product has to meet different requirements in transmission, haze and clarity. The following article describes how these different effects are visually perceived. In addition, practical hints for measuring and analyzing the transparency of special applications are discussed to achieve reliable measurement results.
