A pressurized crystallization point test apparatus for pressurizing a fluid sample and optically detecting the degree of crystallization in the fluid sample while simultaneously measuring the temperature and change in volume of the fluid sample during cooling or heating of the sample is disclosed. The apparatus includes: a cell for containing a fluid sample in an interior of the cell, wherein the cell comprises a first transparent window and a second transparent window; a cooling source for cooling the fluid sample; a pressure source for pressurizing the fluid sample; a temperature sensor positioned in the interior of the cell for measuring the temperature of the fluid sample; an external light source configured to direct light into the cell through the first transparent window; and an external light detector configured to measure the amount of light that traverses the first transparent window, a portion of the fluid sample, and the second transparent window. |
