U-tube oscillation method density meter, electronic liquid density meter is based on the principle of different oscillation frequencies when the double U-shaped tube is filled with different media to measure the liquid density. After the liquid to be measured is pumped into the sensor of the resonant cylinder, the measurement data is processed by the single-chip microcomputer, which is fast and direct, and has high sensitivity. It is composed of a double tuning fork density sensor, a vibrating cylinder circuit, a temperature measuring circuit, a CPU, a display, a constant temperature tank, a liquid inlet pump and a control panel.
Petroleum, diesel, cleaning fluid, lubricating fluid, chemical fluid, flux, crude oil, chemical reagents, stupid, toluene, flavors and fragrances, essential oils, alcohol, beverages and other industries for density testing, for alcohol and sulfuric acid solutions, can be converted concentration!

1. Using the principle of U-tube vibration method, it is suitable for automatic measurement of liquid density
2. Using imported high-speed XFMD chip processing, high sensitivity and accurate data
3. Automatic sampling: adopt Xiongfa special automatic sampling system, automatic quantitative technology, high precision
4. Adopt self-developed residue removal technology to ensure that there is no residue in the sample
5. Constant temperature control: adopt self-developed Peltier refrigeration technology, high cooling efficiency and environmental protection
6. Wall-free treatment: The liquid will leave residual liquid on the inner wall of the oscillation tube during the flow process, which will affect the measurement accuracy. Therefore, by performing wall-free treatment on the inner wall of the oscillation tube, residual liquid on the inner wall of the oscillation tube can be avoided, ensuring The precision of the instrument.
7. Data storage and transmission: built-in memory chip, which can store 80 sets of detection data, and can be recalled and deleted
8. Calibration function: Use pure water at 20°C as the standard to calibrate the instrument, which is a function that cannot be realized by glass density meters.
Insert the sampling tube into the liquid, press the "sampling" button, the liquid will be automatically pumped into the vibrating cylinder, and when the temperature of the machine reaches 20±0.1°C, the temperature and density of the liquid will be displayed directly on the screen.
Drain the liquid in the vibrating cylinder first, and then clean the vibrating cylinder with a suitable cleaning solution until no residue can be seen in the vibrating cylinder.
