NANOCOLOR® Colour
Photometric determination of colours
For determination of the colour intensity one uses the HAZEN scale, which is calibrated with platinum-cobalt chloride standards. In accordance with DIN EN ISO 7887-C1-3 the colouration is measured as spectral absorption coefficient at 3 wavelengths: ~436 nm, ~525 nm, ~620 nm. The colour of the pure sample is measured without any reagents.
