AF710-3 Colorimeter

Color Grading according to AOCS-Tintometer® scale

The Lovibond® AF710-3 is a visual instrument approved by the American Oil Chemists Society (AOCS) for color grading of oils and fats according to AOCS Official Method Cc 13b-45, the Wesson Method. Color 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® Color Scale. The glasses are varied until a color match is found for the light passing through the oil and this color is then expressed in units of red and yellow.

The 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 5-1/4". 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 color glasses. The field of view comprises two circular fields which do not overlap, as required by the AOCS Method.

The Lovibond® AF 710-3 is supplied complete with a set of AOCS-Tintometer® color glasses, two glass sample tubes and a calibrated colored glass filter for regular conformance testing.

The AOCS-Tintometer® Color Scale is a special red and yellow version of the Lovibond® RYBN scale using the AOCS-Tintometer® Red Scale (which is not the same as the Lovibond® standard red scale). The 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 5-1/4".
  • International Standards Approval - The Lovibond® AF 710-3 is a visual instrument approved by the American Oil Chemists Society (AOCS) for color grading of oils and fats.
  • Easy Determination of Color - You can easily measure the color of the sample 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® Color Scale. The glasses are varied until a color match is found for the light passing through the oil. You can then express this color in units of red and yellow.
  • No Excessive Ambient Light - 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 color glasses.
  • Applications Include - Edible Oils and Fats, Household Products, and Petroleum Oils and Waxes
