U-shaped Tube Oscillation Method Densimeter DA-850

Vibrating Liquid Density Meter Method
Method Principle
When a certain volume of liquid fills the U-shaped glass vibrating tube, the change in mass of the substance inside the tube causes a change in the natural or characteristic vibration frequency of the tube. Through precise measurement of the characteristic frequency and mathematical conversion, the sample density is determined.
