Transparency and haze meter

Article No. 4775

haze-gard i
Haze meter according ASTM D1003 and ISO standards

Complete transparency control by taking only one reading:

  • Total transmittance
  • Transmission haze
  • Clarity

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.

  • 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
  • Complete statistics and colorful Pass/Fail analysis
  • Direct data transfer via LAN, USB-port or via USB-stick
  • Professional data documentation and analysis with smart-lab haze software

Knowledge

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.
