The lactometer is a device designed to measure the relative density of a liquid, typically using the principle of buoyancy. It is often calibrated with scales such as specific gravity to provide accurate measurements. In the simulation, you will learn about the lactometer’s structure, working principles, and application in detecting milk adulteration. This comprehensive overview will cover the lactometer’s design, functionality, and significance in various contexts, particularly in assessing the quality and purity of milk through density measurements.
