Electronic balances and their classifications can be divided into the following categories according to their accuracy:
1. Ultra-micro electronic balance: The weighing of ultra-micro balance is 2 to 5 g, and its scale division value is less than 10-6 of the weighing. For example, Uett2 electronic balance of Mettler belongs to ultra-micro electronic balance.
2. Microbalances: Microbalances are generally weighed in the range of 3 to 50g, and their division values are less than 10-5 of the weighing, such as AT21 electronic balances from Mettler and S4 electronic balances from Sartoruis.
3. Semi-micro balance: The weighing of semi-micro balance is generally between 20 and 100 g, and its division value is less than 10-5 of the weighing. For example, Mettler's AE50 electronic balance and Sartoruis' M25D electronic balance belong to this category.
4. Constant electronic balance: This type of balance generally weighs 100 to 200g, and its division value is less than 10-5 of the weighing. For example, Mettler's AE200 electronic balance and Sartoruis' A120S and A200S electronic balances belong to constant electronics. Balance.
5. Analytical balance: In fact, electronic analytical balance is the general name of constant balance, semi-micro balance, micro balance and ultra-micro balance.
6. Precision electronic balance: This type of electronic balance is a collective name for electronic balances with accuracy class II.
