haze-gard i: The objective standard for a clear view

How to control the appearance of transparent materials?

Transparent products can have a milky or fuzzy appearance dependent on their light scattering behavior. The haze-gard i quantifies the visual perception with objective measurement criteria:


  • Total transmittance
  • Transmission haze
  • Clarity

Open and flexible - measure transparency of any product size

The open measurement compartment let’s you work freely to analyze any sample size. Quickly change and position small and large samples.
Dependent on the sample material we designed various sample holders for thin films, sheets, liquids, taber abraded samples which can be easily mounted on the pre-installed track. 

The innovative lighting of the haze-gard i using a long-term stable LED allows measurement without any influence of ambient light.
