How to divide different electronic balance grades?
Electronic Balances are divided into different grades according to the measurement range and graduation value. Generally, electronic balances are divided into grades I, II, III and IV. Share a simple method today to tell you how to divide different electronic balance grades?
As shown below:
In the table, Max is the maximum weighing value, and e is the division value of the verification scale. For example, if you buy an electronic balance with a maximum weighing of 3000g and a minimum reading of 0.01g, then Max=3000g, d=0.01g, that is to say, e=10d=0.1g. n=2000/0.1=30000, according to the table, it can be concluded that the balance is a type II balance, that is, a high-precision balance.
Class I is special standard, class II is Micro Motion, class III is medium standard, and class IV is general standard.
Electronic Balance Classification Table
| accuracy level | Verification scale division value e=10d | Verification scale division number n=Max/e | |
| the smallest | maximum | ||
| Special I | e≤5μg _ 10 μ g ≤ e | 1x10 3 5x10 4 | not limited |
| High II | e≤50m g 0.1g≤e _ | 1x10 2 5x10 3 | 1x10 5 1x10 5 |
| Middle III | 0.1g≤e≤2g _ _ _ 5g≤e _ | 1x10 2 5x10 2 | 1x10 4 1x10 4 |
| Normal IV | 5g≤e _ _ | 1x10 2 | 1x10 3 |
