Automatic Dropping Point and Softening Point. A dropping point system is an analytical instrument used to determine the dropping point and softening point of substances such as greases, pitch, polymers and more. The dropping point is the temperature at which the first drop of molten substance precipitates. The softening point is the temperature at which the molten substance flows a defined distance. With the dropping point system by Mettler Toledo both the dropping point and softening point are obtained fully automatically.
