Colour cum Haze cum Turbidity Meter

Product Details

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). Features： 1. Compliant with both ASTM and ISO standards, accommodating diverse testing requirements.2. The liquid colorimeter can measure color difference, haze, and transmittance, displaying the transmittance spectral curve.3. Easily switch between simple and comparative measurement for straightforward operation.4. Equipped with a 7-inch touchscreen, offering excellent human-machine interaction for convenient operation.5. The colorimeter for liquids color measurement has excellent repeatability, with haze and color difference repeatability ≤ 0.03, and transmittance repeatability ≤ 0.05.6. High accuracy ensures the ability to pass testing at authoritative metrology institutes.7. Offers both vertical and horizontal measurement modes, and is also capable of measuring liquids. 8. Utilize a dual-aperture design with 14mm and 5mm options.9. Equipped with A, C, and D65 standard illuminants. 10. Equipped with PC software for online measurements, supporting data export and printing.
