Project Description

Haze Meter

 Haze Meter

Haze Meter is available for luminous transmittance and haze determination of transparent or semi-transparent specimens with a parallel surface (plastic board and sheeting, etc.), as well as turbidity and clarity determination of liquid samples (water and drinks, etc.).


  • Values of luminous transmittance and haze are simultaneously displayed in the form of average values
  • Haze meter is controlled by micro-computer with LED data display
  • Automatic data processing makes continuous test available
  • Switch between luminous transmittance and haze for determination and calibration is automatically performed
  • Equipped with standard printing port of BCD serial output Test Principle Luminous transmittance is the ratio of the luminous flux passed through the specimen to incident luminous flux; haze is the ratio of scattered luminous flux passed through the specimen to the total transmitted light flux. This instrument conforms to national and international standards: GB 2410-80, ASTM D1003-61(1997), JIS K7105-81
