MEASURING DEVICES

• Freezing Point Principle: According to the methods, the sample is cooled down and stirred. The solid hydrocarbon crystals formation are detected by means of a light beam through fiber optic reflected thanks to a mirror. As soon as crystals are detected, the sample is warmed up until their complete disappearance.
• Freezing Point Device: Light pulsed emission on I.R spectrum through a coaxial fibber optic. Coaxial fibber optic equipped with a mirror
