Method and apparatus for determining the cloud point of oil

An apparatus for the determination of the cloud point of oil having a cooling jacket, a measuring space, a temperature indicator, wherein an oil sample in the measuring space is cooled with the aid of a cooling jacket surrounded by the measuring space and the cloud point is determined from a turning point on the oil cooling curve, wherein the measuring space is essentially shaped like two oppositely oriented hollow cones disposed to face each other flat base to base along a common bottom perimeter or circumference such that each apex points outwards along a mutual parallel axis of said two cones in an opposite direction, or two oppositely oriented hollow rotational semi-ellipsoids disposed to face each other flat base to base along a common bottom oval circumference where each rotational semi-ellipsoid has its rounded surface placed outwards along a mutual parallel axis of revolution said two ellipsoids in an opposite direction, and wherein the point of angle of each of the cones is 25.degree.-100.degree..
