Automatic Saybolt and ASTM Colorimeter

Test Method

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 kerosine, and, in addition, petroleum waxes and pharmaceutical white oils.

Description

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.
