Saybolt Colorimeter

This Koehler K13150 is an automated colorimeter for Saybolt and ASTM Color (Saybolt and Mineral Oil Colorimeter)
~ Designed for color measurement of waxes and other petroleum products
~ Spectral Range 420-710nm

High precision spectrophotometer for objective color analysis of petroleum fuels, oils, waxes and petrochemicals according to the Saybolt and ASTM Color scales. When measuring Saybolt Color of clear, water-white products, the long sample path length enables the K13150 to obtain precise color measurements without multiplying errors.

ASTM Color: For the visual determination of the color of a wide variety of petroleum products, such as lubricating oils, heating oils, diesel fuel oils, and petroleum waxes.
Saybolt Color: Determines the color of refined oils such as undyed motor and aviation gasoline, jet propulsion fuels, naphthas and kerosene, and, in addition, petroleum waxes and pharmaceutical white oils.
