U-tube densitometer

Digipol SeriesU-tube densitometerAdopting the principle of U-shaped tube oscillation method, combined with Peltier precise temperature control technology and high-definition video camera technology, not only provides users with accurate, stable, and reliable test results, but also brings users an efficient and convenient testing experience. High definition videos allow users to easily see if there are any bubbles affecting the sample. By using pulse excitation and high-precision detection technology, users can accurately and quickly measure the sample density and density related parameters.

　　Working Principle:

　　U-tube densitometerBy utilizing the oscillation frequency of a glass U-shaped tube based on electromagnetic induction, that is, by fixing a magnet on the U-shaped glass measuring tube and using an oscillator to generate vibration, the vibration period of the glass tube will be measured by a vibration sensor. Each U-shaped glass tube has its characteristic frequency or vibrates according to its natural frequency. When the glass tube is filled with an object, its frequency will change, and the frequency of different substances will vary. Its frequency is a function of the mass of the material filled in the tube. When the mass of a substance increases, its frequency decreases, that is, the vibration period T increases. When measuring, certain substances are selected as standard substances. After measuring the frequency, the density value of the measured substance is calculated by the difference in oscillation frequency between the measured substance and the standard substance.
