The volumetric density tester is designed based on Archimedes' law of buoyancy. When an object is immersed in a liquid, its buoyancy is equal to the weight of the displaced liquid. By measuring the buoyancy changes of an object in a liquid, combined with the known density of the liquid, the volume of the object can be calculated, and then the density can be calculated based on the mass data of the object. Adopt direct measurement method. For example, for samples with regular shapes, measuring tools can be used to determine their geometric dimensions and calculate their volume; For irregular samples, indirect methods such as drainage may be used to obtain volume information. Integrated high-precision weighing system, automated testing program, and software algorithms. They can automatically complete a series of operational processes from sample placement to data collection and processing, improving work efficiency and accuracy.

Precautions for using the bulk density tester:

1. Operating standards

-Strictly follow the instructions: Strictly follow the operating instructions of the instrument to operate, which is the basis for ensuring correct measurement and obtaining accurate results. Changing the operation process arbitrarily or ignoring certain steps may lead to incorrect measurement results.

-Avoid vibration interference: During the measurement process, the instrument should be kept stable as much as possible to avoid being affected by external vibrations. Because vibration may cause changes in the position of the sample or affect the normal operation of sensors inside the instrument, thereby reducing measurement accuracy.

2. Sample requirements

-Representative sampling: The selected sample should be representative and able to truly reflect the overall characteristics of the tested substance. For uneven materials, multiple sub samples need to be collected from different parts and mixed for measurement.

-Preventing contamination: To prevent the sample from being contaminated, while also avoiding contamination of the instrument by the sample. After use, the instrument and sample container should be cleaned in a timely manner, especially after coming into contact with corrosive or toxic substances.

3. Environmental conditions

-Temperature control: The ambient temperature can have an impact on the measurement results, especially for liquid samples and some temperature sensitive materials. Therefore, measurements should be taken within the specified temperature range, and temperature stability should be maintained as much as possible during the measurement process.

-Humidity impact: High humidity environments may cause problems such as rusting of instrument components, decreased electrical performance, and may also affect the properties of certain samples. When using and storing instruments, attention should be paid to controlling the environmental humidity.

4. Safety precautions

-Electrical safety: Ensure good grounding of instruments to prevent electric shock accidents. During use, do not touch the high-voltage components inside the instrument to avoid injury.

-Chemical protection: If it involves using chemical reagents to assist in measurements (such as certain special cleaning agents or solvents), appropriate personal protective equipment such as gloves, goggles, etc. should be worn and operated in a well ventilated environment.

5. Maintenance and upkeep

-Regular inspection: Regularly inspect and maintain the instrument, including checking whether the various components of the instrument are working properly, whether the connection lines are loose, and whether the sensors are sensitive. Timely detection and resolution of problems can extend the lifespan of the instrument and ensure measurement accuracy.

-Storage conditions: When the instrument is not in use, it should be stored according to the prescribed storage conditions, avoiding adverse factors such as direct sunlight, humidity, and high temperature that may damage the instrument.
