Electronic balance is a commonly used weighing tool in the laboratory, which is used to weigh the mass of objects. It is often used for sample weighing, reagent weighing, etc. Balances with different accuracy and range have different uses.

Laboratory electronic balances can be divided into the following categories according to accuracy:

1. Ultra-micro electronic balance: The maximum weighing capacity is 2 to 5g, and its scale graduation value is less than 10-6 (power) of the (maximum) weighing value.

2. Micro balance: The weighing range is generally from 3 to 50g, and its graduation value is less than 10-5 of the (maximum) weighing value.

3. Semi-micro balance: The weighing range is generally between 20 and 100g, and its graduation value is less than 10-5 of the (maximum) weighing value.

4. Constant electronic balance: The maximum weighing capacity is generally between 100 and 200g, and its graduation value is less than 10-5 of the (maximum) weighing value of.

5. Analytical balance: In fact, electronic analytical balance is a general term for constant balance, semi-micro balance, micro balance and ultra-micro balance.

6. Precision electronic balance: This type of electronic balance is a general term for electronic balances with level II accuracy.

Laboratory electronic balance is a widely used accurate mass measuring instrument. It overcomes the shortcomings of traditional steelyard scales and pan scales such as inaccuracy, slow speed. It has the advantages of fast weighing, reliable accuracy, automatic calibration, and automatic wave weight.
