Abstract
An integrated test device adapted to perform tests on a single aliquot of a liquid sample. The test device includes a viscosity test cell adapted to perform viscosity tests on the liquid sample; a freeze point test cell adapted to perform freeze point tests on the liquid sample; a sample injection port adapted to load the single aliquot of the liquid sample into both of the viscosity test cell and the freeze point test cell, where the viscosity test cell and the freeze point test cell are connected in parallel to the sample injection port; a data processing unit to collect data from the viscosity test cell and the freeze point test cell and process the data, the data processing unit performing calculations to determine temperatures at any specified viscosity above a freeze point and checks of integrity of the viscosity measurements.
