Abstract
An apparatus and method for determining at least one of the temperatures at which a petroleum product will manifest delayed haze and the temperature at which haze will not exist in the product is provided. The apparatus comprises a container for holding a sample of the product, a light source, light detector, heaters and coolers combined with microprocessor means for storing and analyzing at least one of light transmitted or scattered by the sample. Measurements are useful in determining the haze properties of the product and also for controlling a dehazing process to meet target haze properties.
