Read： 402 Time：7months ago Source：Transform the World with Simplicity

In daily life, we often need to use pan indicator to detect the PH value of an object or perform a pH test. However, in the process of using pan indicator, we also need to pay attention to some matters and master some skills. Let's take a closer look.

before using pan indicator, we need to pay attention to keep it clean. Make sure that the containers, glass rods and other tools used are clean to avoid the influence of impurities on the test results.

we need to choose the kind of pan indicator carefully. Different types of pan indicators are suitable for different test environments and substances, so you need to read the product manual carefully when choosing to confirm its scope of application.

In the process of using pan indicator, we need to pay attention to the control of usage. Too little usage may not be enough to accurately display the pH of the target substance, while too much usage may cause distortion of the test results. Therefore, we need to carefully control the usage according to the actual situation.

In order to obtain accurate test results, we need to ensure the stability of the test environment. Avoid testing in an environment with poor ventilation or large temperature changes to avoid external factors affecting the test results.

in addition to the above precautions, we also need to master some skills.

we need to be familiar with the color change law of pan indicator. Different pan indicators will show different colors under different PH values. By being familiar with these laws, we can more accurately judge the pH of the target substance.

we need to master the dropping technique of pan indicator. In the process of adding pan indicator, it needs to be added slowly and evenly to avoid the deviation of test results caused by too fast and too fast dropping.

After using the pan indicator, we also need to clean the tools in time to avoid the impact of pan indicator residue on the next test results.

, we also need to properly store the pan indicator to avoid exposure to the sun or high temperature environment, so as not to affect its use effect.

In general, using pan indicator is a relatively simple operation, but we also need to pay attention to some details during use. It is hoped that the introduction of this article can help us to use pan indicator better and obtain accurate test results.
