Pt-Co / Hazen / APHA platinum and cobalt color scale refers to the use of different concentrations of Pt-co solution for chromaticity grading. The concentration ranges from 0-500, also known as Hazen and APHA color scale.
CHNSpec Tech designed a heating system for transmittance color measurement. This device can heat the liquid temperature into a specific temperature to measure color, transmittance,absorbance, APHA,Pt-Co,Hazen,etc.
Recently, we have done a project for a customer to measure chemical powder reflectance and liquid transmittance measurement with our benchtop spectrophotometer CS-820. Now we will introduce the operation.
Gardner color scale is used to represent yellowness of transparent liquid. It is determined by pouring the sample into a glass cell and comparing its lab value with the standard color solutions'. We introduce how to measure with with Gardner color spectro
There are many powdered products, powder coatings, titanium dioxide, flour and so on. However, many customers do not know how to measure the color difference of the powder.In fact, the method is very simple, let me introduce how to use it.
