High-Precision Laboratory Determination of Density and Concentration
 
RHOTEC L determines the density and concentration of manually injected samples, such as extract, alcohol, sugar, acids, alkalis and solvents. The instrument is designed for laboratory applications requiring high sensitivity and accuracy.
 
Measuring Principle
 
The sample flows through a thin U-shaped tube that is electromagnetically excited at its resonant frequency. Density changes affect the oscillation behaviour. A product-specific mathematical polynomial describes the relationship between density and concentration.
