1、 Operating standards

1. Read the operation manualBefore using the densitometer, be sure to carefully read the operating manual, familiarize yourself with the functions, characteristics, and safety precautions of the instrument.
2. Check the integrity of the instrumentCheck if the densitometer is damaged and ensure that all accessories are complete and functioning properly.
3. Preheating instrumentAfter turning on the power, give the instrument sufficient preheating time to reach a stable working state.
4. Calibration instrumentSelect a standard substance with a density similar to that of the liquid being tested for calibration to ensure measurement accuracy. During the calibration process, ensure that there are no bubbles in the measuring cell and complete the calibration according to the instructions in the operating manual.
5. Set measurement itemsSelect measurement parameters such as density, relative density, alcohol content, or sulfuric acid concentration as needed, and set corresponding measurement units and temperature coefficients.

2、 Environmental requirements

1. Avoid direct sunlight and vibrationThe density meter should be placed in a place away from direct sunlight and vibration to ensure the accuracy of the measurement results.
2. Keep the environment clean and hygienicEnsure a clean and hygienic measurement environment, avoid excessive dust and magnetic field interference, which may affect the measurement performance of the densitometer.
3. Stay away from heat sourcesThe instrument should be kept away from heat sources such as electric heaters, heaters, and air conditioners to prevent deformation or damage caused by heat.

3、 Sample processing

1. Selection of measurement samplesThe measurement sample should be free of solid particles as much as possible to avoid scratching the U-shaped tube and affecting subsequent measurements.
2. Measurement of low viscosity samplesManually connect the injection tube to the instrument and ensure that there is no air leakage. Immerse the injection tube into the sample and slowly draw the sample into the measuring cell to ensure that there are no bubbles before reading the measurement value.
3. Measurement of high viscosity samplesInject the sample using a plastic syringe and ensure that there are no bubbles in the measuring cell, then take a reading.

4、 Instrument maintenance

1. Cleaning measuring tankAfter the test is completed, the measuring cell should be emptied and cleaned repeatedly, and the outer shell should be wiped dry with a soft cloth or tissue. When cleaning the measuring tank, a solution or cleaning agent that does not damage the instrument should be used.
2. Regularly inspect the hoseThe hose used for sample injection through the hose pump is prone to damage and should be regularly inspected and replaced in a timely manner.
3. Storage of instrumentsThe instrument should be placed in a ventilated, cool, and dry environment, away from water vapor. Please empty the measuring tank before storage to avoid liquid residue causing damage to the instrument.
