Overview

G amp; GJ323BF Shuangjie Instrument Factory Phone 220g/0.001g Electronic Balance JJ423BF $r $n Electronic balance is a precision weighing instrument used by many customers because of its simple operation and accurate weighing. However, some customers are confused by the internal and external calibration issues of the electronic balance when choosing it, and do not know how to choose. Even some consulting customers are unaware of the difference between internal and external electronic scales. Let's talk about the internal and external calibration issues of electronic scales today.

In fact, the accuracy of an electronic balance is not related to internal or external calibration, but mainly depends on the grade of the weights and the quality of the electronic balance sensor. Generally, the grade of the external weights and internal weights that come with a newly manufactured balance is the same, so there is no difference. However, over time, the wear and tear of the external weights is generally greater than that of the internal weights: they will be affected by dust, acid and alkali corrosion, and a fingerprint can weigh tens of micrograms. If not stored properly, there may be cases of loss. So if the annual measurement inspection fails, the weights need to be replaced. A balance with built-in weights generally does not experience the above situation, and deviations can be corrected by modifying the calibration program parameters of the balance. Although the internal calibration balance is about 20% more expensive than the external calibration, it is easy to use and has obvious advantages in use.

Therefore, there is no difference in accuracy between internal and external schools, and everyone can make purchases based on their budget. After all, the price of electronic scales also varies greatly. If you still have any questions or want to learn more about electronic scales, you can consult us directly.
