The 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 allow a colour match to be found from the light passing through the oil and this colour is then expressed in units of Red and Yellow.
