Colour cum Haze cum Turbidity Meter

Colour Measurement: A white light source passes through (or reflects from) the sample.Detectors measure the intensity at different wavelengths (usually using filters or spectrophotometric methods).The colour is expressed in standard scales (CIE, Hunter Lab, L*, a*, b*, etc.).Haze Measurement (for transparent/solid sheets or liquids)Haze is the fraction of light scattered at large angles after passing through the material.A detector measures transmitted light at a small angle from the main beam to quantify the "cloudiness" of transparent solids (plastics, glass) or liquids.Turbidity Measurement (mainly for liquids)Based on the Tyndall effect (scattering of light by suspended particles).A detector is placed at 90° to the incident light beam to capture scattered light.The intensity of scattered light is correlated to turbidity (NTU units).
