How are the accuracy grades of electronic scales classified?

The accuracy grades of electronic scales can be classified based on the verification division value, mainly divided into the following grades:
Class I scale: Generally refers to electronic balances with a verification division value of one part per hundred thousand or more. The measurement range of this type of scale is also very small, belonging to micro-electronic scales, mainly used in scientific research laboratories.

Class II scale: Electronic balance products with a verification division value ranging from one ten thousandth to one hundred thousandth.

Class III scale: Electronic scales with a verification division value ranging from one thousandth to one ten thousandth. This is the most commonly used type, such as large and small floor scales, electronic platform scales, and electronic hanging scales all belong to Class III scales.

Class IV scale: Electronic scales with a verification division value ranging from one hundredth to one thousandth, used in commercial settings where requirements are not high.

电子秤的精度等级可以根据检定分度值进行划分，‌主要分为以下几个等级：

I级秤：‌通常是指检定分度值达到十万分之一以上的电子天平，‌这类秤的量程也非常小，‌属于微量电子秤，‌主要用于科研实验室。

II级秤：‌检定分度值在一万到十万之间的电子天平类产品。

III级秤：‌检定分度值在一千到一万之间的电子秤，‌为常用，‌比如大、‌小地磅、‌电子台秤和电子吊秤都属于三级秤。

IV级秤：‌电子秤检定分度值在一百到一千之间，‌用于商业，‌要求不高的场合。
