Electronic balance classification and maintenance use

Under normal circumstances, electronic balances have different accuracy of use and different weighing objects. Therefore, the classification of electronic balances is also a lot. There are roughly six categories, including:

1. Semi-micro balances: Semi-micro balances are generally weighed from 20 to 100 g, and their graduations are smaller than the (maximum) 10–5.

2. Ultra-micro electronic balance: The maximum weighing capacity of an ultra-microbalance is 2 to 5 g, and the scale division value is smaller than the (maximum) 10-6.

3, micro-balance: Weighing microbalance is generally in the 3 to 50g, the division value is less than (maximum) weighing 10-5.

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

5, precision electronic balance: This type of electronic balance is the accuracy level of the electronic balance of Class II collectively.

6. Constant electronic balance: The maximum weighing of such a scale is generally 100 to 200 g, and the division value is smaller than the (maximum) weighing of 10-5.

The other explanation is the maintenance and use of electronic balances.

1. When weighing volatile and corrosive articles, place them in a closed container to avoid corrosion and damage to the electronic balance.

2. Place the balance on a stable work bench to avoid vibration, air flow, and sunlight. 3. Adjust the bubble of the electronic balance to the middle position before use.

4, often on the electronic balance for self-school or regular outside school to ensure that it is in the best condition.

5, if the electronic balance failure should be promptly overhauled, not with "disease" work.

6, the operating balance can not be overloaded to avoid damage to the balance.

7. The electronic balance should be warmed up according to the instructions.

To some extent, the classification of electronic balances may not be of great concern to non-professionals, but it is essential knowledge for each manufacturer and user for its maintenance and use!
