Electronic Balance

Electronic balance, used to weigh the mass of objects. Electronic balances generally use strain gauge sensors, capacitive sensors, and electromagnetic balance sensors. Strain sensor has simple structure and low cost, but its accuracy is limited.

Electronic balances and their classifications Electronic balances can be divided into the following categories according to their accuracy:

1. Ultra-micro electronic balance: The maximum weighing capacity of an ultra-micro balance is 2 to 5g, and its scale graduation value is less than 10-6 (maximum) weighing. For example, Mettler's UMT2 electronic balance belongs to ultra-micro electronic balance.

2. Microbalance: Microbalances generally weigh between 3 and 50g, and their graduation value is less than the (maximum) weighing value of 10-5, such as Mettler's AT21 electronic balance and Sartoruis' S4 electronic balance.

3. Semi-micro balance: The weighing of a semi-micro balance is generally between 20 and 100g, and its graduation value is less than the (maximum) 10-5 of the weighing. Such as Mettler's AE50 electronic balance and Sartoruis' M25D electronic balance, etc. Such.

4. Constant electronic balance: The maximum weighing of this kind of balance is generally 100 to 200g, and its graduation value is less than the (maximum) weighing 10-5, such as Mettler's AE200 electronic balance and Sartoruis's A120S and A200S electronic balances. The average belongs to the constant electronic balance.

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 an accuracy level of Level II.

It is characterized by accurate and reliable weighing, fast and clear display, automatic detection system, simple automatic calibration device and overload protection.
