The osmometer is a precision instrument for measuring the osmotic pressure of solutions. Based on the advanced osmosis principle, it accurately determines the osmotic pressure value by detecting the pressure difference generated by the solution on a semi - permeable membrane. The instrument uses high - precision sensors and precise mechanical structures, and is made of chemically - resistant materials to ensure long - term stable operation. Its advantages are high measurement accuracy and fast response speed. Widely used in fields such as medicine, biology, and food, it provides key data for solution concentration control and product quality testing to ensure the stability and effectiveness of products.
