How to ensure the precision of the electronic balance in the experimental environment with large airflow?

Electronic balances are instruments that are often used in experiments. Balances that use electromagnetic force to balance the weight of an object are called electronic balances. The electronic balance is accurate and reliable, and the display is fast and clear. Obtaining data is often very important to the experiment, it is related to the accuracy of the experimental results, and even relates to the success or failure of the experiment.

However, sometimes the experimental environment may not be satisfactory. Although there are many considerations for using electronic balances, if conditions are limited and experiments have to be conducted, then there may be many situations. The most common is the large air flow in the test environment. For example, the wind from an air conditioner or a fan, the movement of the air by a person moving around or the test site outdoors, etc. will make the precision instruments such as electronic balances unstable.

In this environment, the data measured by the electronic balance will naturally have a large error, which is not conducive to the experiment. At this time, only small measures are needed to reduce errors and facilitate experimentation. The simplest and most effective measure is to make a windshield with an electronic balance, using waste paper bins, plastics, and other materials. Covering the balance, the balance display window and loading and unloading areas can leak out. This balance can try to avoid the impact of the air flow.

In addition to installing the windshield to the balance, in order to be precise in the experiment, the electronic balance needs to be fully warmed up and corrected. After calibration, multiple measurements can be performed and averaged. The result of this measurement will be relatively accurate, and the impact of airflow on the balance will be minimized.
