HWMD-300 Constant Temperature Liquid Density Meter

HWMD-300Constant temperature liquid density meter

Constant temperature liquid density meter-The U-tube oscillation method densitometer is used to measure liquid density based on the principle that the oscillation frequency is different when the double U-tubes are filled with different media.Product application range: density test for petroleum, diesel, detergent, lubricant, chemical liquid, flux, crude oil, chemical reagent, benzene, toluene, essence, spice, essential oil, alcohol, beverage and other industries. For alcohol and sulfuric acid solution, the concentration can be converted!

After pumping the liquid to be tested into the resonant cylinder sensor, the program processes the measurement data quickly, directly, and with high sensitivity.

It is composed of a double tuning fork density sensor, a vibrating tube circuit, a temperature measurement circuit CPU、 It consists of a monitor, a thermostatic bath, an inlet pump, and a control panel

IIIcharacteristic:

1. Adopting the principle of U-shaped tube vibration method, suitable for automatic measurement of liquid density

2. Using imported advanced XFMD chips for processing, high sensitivity and accurate data

3. Automatic sampling: using male hair automatic injection system, automatic quantification technology, high accuracy

4. Adopting self-developed residual removal technology to ensure that the sample is free of residue

5. Constant temperature control: using self-developed technologyPeltier refrigeration technologyHigh refrigeration efficiency and environmental friendliness

6. Non hanging wall treatment: During the flow of liquid, residual liquid will be left on the inner wall of the oscillating tube, which will affect the measurement accuracy. Therefore, by performing non hanging wall treatment on the inner wall of the oscillating tube, residual liquid on the inner wall of the oscillating tube can be avoided, ensuring the accuracy of the instrument.

7. Data storage and transmission: Built in storage chip, capable of storing 80 sets of detection data, and can be recalled and deleted

8. Calibration function: Use 20 ℃ pure water as a standard to calibrate the instrument, which is a function that glass density meters cannot achieve.

4Test steps:

Insert the sample tube into the liquid, press the "Sampling" button once, and the liquid will be automatically drawn into the shaker. Wait for the machine to reach a constant temperature of 20 ± 0.1 ℃, and the screen will directly display the temperature and density values of the liquid

5Automatic cleaning:

First, drain the liquid inside the vibrating tube, and then clean the vibrating tube with a suitable cleaning solution until no residue is visible inside
