Product Description

The osmolality meter , based on Raoult's freezing point theory and the proportional relationship between the freezing point depression and the molar concentration of a solution, uses a highly sensitive temperature sensing element to measure the freezing point of different solutions, thereby determining the osmolality of the measured solution. It is widely used in the testing and research of osmolality in pharmaceuticals, drug analysis, biology, food, and medical fields.
