Precision Balance

Pruiste is a precision balance factory in china, precision balance is an indispensable high-precision weighing equipment in laboratories, industrial production, and scientific research fields. Its measurement accuracy can usually reach 0.1mg to 0.01mg, or even higher. This type of instrument can accurately measure the mass of substances through electronic sensor technology, providing reliable data support for fields such as chemical analysis, pharmaceutical research and development, and materials science.

Working principle and technical characteristics

Modern precision balances mainly operate based on the principle of electromagnetic force balance. When the sample is placed on the weighing plate, the sensor inside the balance will generate an electromagnetic force equal to the weight of the sample to maintain balance. The magnitude of this electromagnetic force is converted into a digital signal through precision electronic components and ultimately displayed on the screen in units of mass.

The key technical features include:

1. High sensitivity sensor: using advanced strain gauges or electromagnetic force compensation technology
2. Temperature compensation system: automatically corrects errors caused by environmental temperature changes
3. Seismic design: reduce the impact of external vibrations on measurement results
4. Automatic calibration function: Built in weights or external calibration programs ensure long-term accuracy

Main types and application areas

1. Analytical balance: accuracy of 0.1mg, widely used in laboratory routine analysis
2. Semi micro balance: accuracy of 0.01mg, suitable for weighing trace samples
3. Microbalance: with an accuracy of up to 0.001mg, used for ultra trace analysis
4. Ultra micro balance: highest precision level, up to 0.0001mg

Application area coverage:

1. Pharmaceutical industry: raw material ratio, quality control
2. Chemical research: precise weighing of reagents
3. Materials Science: Measurement of Nanomaterials
4. Food Industry: Composition Analysis
5. Environmental monitoring: pollutant detection

Purchase and Use Guide

Selection considerations:

1. Maximum weighing range and accuracy requirements
2. Environmental conditions (temperature, humidity, vibration)
3. Special functional requirements (anti-static, anti-corrosion, etc.)
4. Calibration method and frequency
5. Data interface and software compatibility

Precautions for use:

1. Avoid using in environments with strong airflow, vibration, or electromagnetic interference
2. Regularly calibrate, it is recommended to perform daily calibration before each use
3. Appropriate protective measures should be taken when weighing volatile or corrosive substances
4. Keep the balance clean and prevent powder or liquid from entering the interior
5. Use appropriate containers to avoid static electricity interference

Maintenance and troubleshooting

Daily maintenance:

1. Regularly clean the weighing plate and casing
2. Check the horizontal status to ensure that the balance is placed steadily
3. Regularly power on when not in use for a long time
4. Replace the desiccant according to the manufacturer's recommendations

Common problem handling:

1. Unstable display: Check if there is any vibration or airflow in the environment
2. Calibration failed: Confirm that the calibration weights are clean and meet specifications
3. Display error code: Refer to the manual or contact technical support
4. Slow response: Check the power supply or consider sensor issues

The importance of precision balance as a fundamental equipment for modern scientific research and industrial production is self-evident. Correctly selecting, using, and maintaining precision scales not only ensures the accuracy of measurement data, but also extends the service life of equipment, providing reliable support for scientific research and production.
