C7 Saybolt Colour Number (ASTM D 156)
The Saybolt colour scale is used to match colours of refined oil
products like fuel and kerosene or also petroleum waxes and pharmaceutical white oils. Its
colorimetric characteristics are comparable with those of the Hazen scale (APHA). The Saybolt
scale begins at +30 (brightest coloration, corresponding to approx. 8-10 Hazen) and ends at -16
(stongest coloration, corresponding to approx. 350 Hazen).
Measurements can be made with cuvettes of 11mm or 50mm path lengths. The greater the path
length, the better the measuring accuracy (50mm recommended).
1. Fill the sample liquid into a cuvette and insert it into the
corresponding compartment.
2. After the measurement, the colour value is indicated in the
configured colour system on the display.
3. Now press the -key (DIM) until the Saybolt number
