1. Main uses of the Zeal D4020/FL/84F
Milk density measurement: Determines the relative density of raw, fresh or processed liquid milk.
Screening for water adulteration: Added water generally reduces milk density, which may indicate dilution.
Milk quality control: Helps identify density readings that differ from the expected range for the type of milk being tested.
Dairy processing and collection: Useful for routine checks at milk collection centres, dairy plants and food laboratories.
Laboratory teaching and research: Demonstrates density measurement and the physical properties of milk
