Electronic density balance is widely used in the rubber industry, powder metallurgy industry, gold jewelry testing industry, machinery processing industry, wire and cable manufacturing, footwear, cosmetics, food industry, automotive manufacturing, teaching and research institutions and other institutions . It is mainly used to measure the density of solids, liquids, floating bodies, particles, powders, viscous bodies, sponges, and the like. The electronic density balance uses a high-precision weighing system and a rigorous measurement program, so that the density value is directly displayed on the display of the electronic balance, which greatly meets the needs of various industrial applications and scientific research departments for density measurement. Application of liquid density measurement:
1. First, prepare an arbitrary sample (preferably a glass ball or a stainless steel ball that will not be corroded).
2. Mount the specific gravity density bracket above the balance.
3. Place the sample on the tray and measure the weight in the air. The density balance is automatically recorded.
4. The sample is then placed in a hanging basket and placed in a glass filled with purified water to measure the weight of the sample in water. The density scale is also recorded automatically.
5. The density balance will automatically record the weight in the air - the weight in the water (eg 10g - 7.128g) = the volume of the sample in cm3 (2.872cm3). This weight difference is the volume of the sample and the unit is cubic centimeters.
6. The balance will automatically calculate and display the density of the sample. At this point, please memorize this volume value and use it later!
7. Next, enter the balance into the menu for measuring the liquid density. You will be asked to enter the volume of the specific gravity hammer according to the operating instructions. At this time, it is necessary to input the just measured weight difference: 2.872CM3 (cubic centimeters).
8. After entering 2.872, measure the weight of the air in the tray as prompted by the balance and place it in the liquid you want to measure. After measuring the weight in this liquid, the balance will automatically calculate and display the density value of the measured liquid. .
Precautions:
1. When measuring the weight difference, use pure water, if ultra pure water is better! At the same time, the temperature of the water will affect the specific gravity of the water. Therefore, the water temperature compensation should be set in the balance test procedure to reduce the measurement error.
2. In the daily solid density process, due to the different appearance and surface roughness of the tested product, it is easy to generate air bubbles on the surface when measuring the weight of water, so that the weight measurement in the water is inaccurate. For this reason, it is recommended that the product to be tested be shaken in alcohol before putting the product under test into the water.
3. Density bracket installation should be stable, can not shake! Shaking affects the accuracy of weighing!
4. The hanging basket should be stable in the water and cannot be shaken! Shake affects the accuracy of weighing! The steel wire of the density basket should be as thin as possible while being steely.
5. After measuring the weight difference, replace the water in the cup with the liquid to measure the density.
6. Since the weighing error of the balance will directly affect the accuracy of the specific gravity hammer volume, this specific gravity hammer volume measurement method is only used for routine use!
7. If you need to use a more accurate weight hammer, you need to calculate the weight of the hammer or prepare a precise weight value in advance (imported Sartorius electronic balance liquid density measuring device is equipped with a precision weight hammer).
8. Because the sample in this measurement method will produce errors in both air and water measurements, it is recommended that the density be averaged after measuring at least three times.
9. Sartorius balance with precision weighing temperature compensation function, can be equipped with special solid and liquid density devices, and conduct density measurement safely, accurately and reliably.
