If the quality of the ph electrode is good, the ph meter must not be bad
The pH electrode is the main part of the pH meter to measure the acidity value of the solution. Its quality directly determines whether the instrument can be used normally. In general, electrodes also have a shelf life. Starting from the production date marked on the electrode of the instrument, the performance of the electrode should meet all the requirements of the instrument measurement within one year. In a certain period of time, if the electrode cannot be used normally due to problems, you can consult the manufacturer for repair or replacement. It should be noted that the guarantee time is not used here, and generally it cannot be understood that the life of the electrode is one year, because the life of the electrode is related to other factors.
1. Medium.
If the properties of the measured media are different, the same pH electrode will have different effects on the pH meter. For example, media with strong acids and bases are much more corrosive than cleaning media.
2. Use time.
Instruments that are used continuously for long periods of time will naturally wear out faster than those that are used occasionally.
3. Whether it is cleaned and maintained.
The electrodes of the pH meter also need frequent cleaning and maintenance. In general, electrodes do not fail easily. If it is not completed on time, it may be caused by improper operation. After each test, the instrument should be cleaned to avoid the corrosive effect of the medium.
The measurement of the pH value of a solution is a very precise job, which requires the use of a professional measuring instrument, a pH meter. In order to obtain the ideal effect, the instrument with the corresponding ion selective electrode can also measure the MV value of the ion electrode potential. During use, the pH electrode must be kept on at all times.
