U- Shaped Vibrating Tube Densitometer
The fully automatic densitometer adopts the principle of U-tube oscillation method, effectively combining Paltier precise temperature control technology and high-definition video camera technology. It not only provides users with accurate, stable, and reliable test results, but also brings users an efficient and convenient testing experience. High definition videos can easily see whether there are bubbles in the sample. Pulse excitation and high-precision detection technology are used to facilitate users to accurately and quickly measure sample density and density related parameters.
Testing principle: Inject a small amount of sample into a temperature controlled sample tube, record the vibration frequency or period, and calculate the density of the sample using the previously obtained sample tube constant. The constant of the sample tube is determined by the vibration frequency when the sample tube is filled with a known density calibration solution. The instrument will directly display the density value after the sample is injected into the sample tube.
