Visual Colorimeter Measuring AOCS-Tintometer® Colour
The Lovibond® AF710-3 is a visual instrument approved by the American Oil Chemists Society (AOCS) for colour grading of oils and fats according to AOCS Official Method Cc 13b-45, the Wesson Method. Colour is determined by comparing light transmitted through a column of oil with that transmitted through a series of red and yellow glasses calibrated in accordance with the AOCS-Tintometer® Colour Scale. The glasses are varied until a colour match is found for the light passing through the oil and this colour is then expressed in units of red and yellow.

The Tintometer AF 710-3 accommodates the special flat-bottomed glass sample tubes specified in the AOCS Official Method Cc 13b-45, which are marked to indicate an oil column of 1/2", 1" and 51/4". The tube holder, which prevents light from entering the sides of the tubes, houses two tubes, one containing the sample and the other allowing an equal amount of light to reach the colour glasses. The field of view comprises two circular fields which do not overlap, as required by the AOCS Method.

The AOCS-Tintometer® Colour Scale is a special red and yellow version of the Lovibond RYBN scale using the Colour Scale AOCS-Tintometer® Red Scale (which is not the same as the Lovibond standard red scale). The AF710 - 3 includes the following standard set of glasses:

Red 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 1.0, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0, 7.0, 7.6, 8.0, 9.0, 10.0, 11.0, 12.0, 16.0, 20.0
