HM-150L2

Hazemeter

The HM-150L2 is designed to measure total light transmittance, diffuse transmittance, and haze. It is ideally suited to make these measurements for light transmissible materials such as plastics, glass. Employing a double-beam system, highly accurate and repeatable transmittance and haze measurements can be realized. Internal switchable filters tune the light source to the spectral characteristics of CIE standard photometric observer and CIE standard illuminant D65, but also the combination including CIE standard illuminant A. A personal computer is used for interface, calculation, and control. Several useful functions, such as average calculation, and output by printer are available. Vertical installation and horizontal sample set-up allows the operator to use the instrument easily and more effectively.

The HM-150L2 conforms to most national and international haze standards, including:

  • IS0 14782 Determination of haze for transparent materials
  • IS0 13468-1 Determination of the total luminous transmittance of transparent materials
  • ASTM D1003 Haze and Luminous Transmittance of Transparent Plastics (D1003 is approximated)
