Specifically designed to measure the transmitted colour of transparent liquids and solids, ColorQuest XT colorimetric spectrometers are available now from Novasys Group .
Products such as resins, solvents, acids, perfume and varnishes can be measured using the APHA/PtCo/Hazen and Gardner colour scales with these devices.
In addition, the Saybolt or ASTM colour scale can be used to measure gasoline, white spirits, kerosene, heating oils, lubricating oils and petroleum waxes.
Beer is measured using the ASBC or EBC scales, with the ADMI scale used for accurate measurement of dyestuff in wastewater.
Widely used colour scales and indices are also included for applications that involve transmission in the food, pharmaceutical and plastics industries.
These colorimetric spectrometers eliminate the subjectivity inherent in visual comparison methods, allowing for greater sensitivity and maximal repeatability.
