Haze-gard i

Product Ref: Haze-gard i

The BYK Haze-gard i quantifies the visual perception of films with objective measurement data.

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

Haze-gard i controls complete transparency by taking only one reading.


Haze and transmittance control according to international standard methods with one unit:

  • ASTM D1003 – illuminants C and A Non-compensated method
  • ISO 13468 – illuminant D65 Compensated method haze-gard i displays all results simultaneously – well prepared for any customer specification.


With state-of-the-art optics and LED technology the haze-gard i delivers an unprecedented performance:

  • Reference beam, self-diagnosis and enclosed optics
  • LED light source assures long-term stable results for many years: 10 year warranty on the lamp life!
  • Automatic, long-term calibration – operator friendly and safe

Superior repeatability and inter-instrument agreement are guaranteed.
