Electronic Balance

Pruiste is a electronic balance factory in china, electronic balance is a precision instrument that uses the principle of electromagnetic force balance for mass measurement, and has become an indispensable measuring tool in modern laboratories, industrial production, and scientific research. Compared to traditional mechanical scales, electronic balance have significant advantages such as high accuracy, easy operation, and rich functions.

The core components of an electronic balance include a weighing sensor, an electromagnetic force compensation system, an analog-to-digital converter, and a microprocessor. When an object is placed on a weighing plate, the sensor converts the gravity signal into an electrical signal. After amplification and analog-to-digital conversion, the microprocessor calculates and displays the mass value.

The main types of electronic balance

Classified by accuracy

1. Analytical balance: The highest accuracy can reach 0.0001g (0.1mg), mainly used for laboratory precision analysis
2. Precision balance: accuracy between 0.001g-0.01g, suitable for routine laboratory work
3. Industrial balance: accuracy above 0.1g, used for quality control in industrial production

Classified by range

1. Microbalance: The maximum weighing is generally between 2-100g
2. Semi micro balance: maximum weighing of 100-500g
3. Constant balance: maximum weighing 500g-5kg
4. Large capacity balance: weighing a maximum of 5kg or more

Key technical indicators of electronic balance

1. Weighing range: the minimum to maximum mass values that the balance can measure
2. Readability: The minimum amount of mass change that a balance can display
3. Repeatability: The consistency of weighing the same object multiple times under the same conditions
4. Linear error: the deviation between the actual measured value and the ideal linear relationship
5. Response time: The time required from loading the sample to displaying stable results
6. Environmental adaptability: sensitivity to environmental factors such as temperature, humidity, and vibration

Advanced features of electronic balance

1. Modern electronic balance have developed various advanced functions:
2. Automatic calibration: Built in weights or automatically calibrated through external commands
3. Animal weighing: a dynamic weighing mode specifically designed for measuring live animals
4. Percentage Weighing: Quickly calculate the percentage of sample to reference amount
5. Density measurement: combining auxiliary devices to measure the density of solids or liquids
6. Statistical calculation: Automatically calculate statistical measures such as mean and standard deviation
7. Data interface: equipped with data transmission interfaces such as USB, RS232, or Bluetooth

The use and maintenance of electronic balance

Correct usage method

1. Horizontal adjustment: Ensure that the balance is level before use
2. Preheating: High precision scales require a preheating time of 30 minutes to 2 hours
3. Calibration: Regularly calibrate to ensure measurement accuracy
4. Environmental control: Avoid airflow, vibration, and temperature fluctuations

Routine Maintenance

1. Regularly clean the weighing plate and casing
2. Avoid overloading during use
3. Use appropriate containers to hold samples
4. When not in use for a long time, the power should be disconnected
5. Regularly conduct performance validation

Application fields of electronic balance

1. Research Laboratory: Chemical Analysis, Materials Research, etc
2. Pharmaceutical industry: raw material weighing, formula preparation
3. Food industry: formula control, quality testing
4. Educational institutions: Chemistry and Physics Experiment Teaching
5. Jewelry industry: weighing of precious metals and gemstones
6. Environmental Monitoring: Sample Collection and Analysis

With the advancement of technology, electronic balance is developing towards higher precision, stronger functionality, and more convenient operation, providing more reliable solutions for precise measurements in various industries. When choosing an electronic balance, factors such as accuracy, range, and functionality should be considered based on actual needs to ensure that the most suitable product is selected.
