Factors Influencing Electrode Life
Generally, when asked about the life of electrodes, many experts and teachers, including manufacturers, will say that it is one year, which is not accurate. In addition to electrode quality and production date, electrode life is determined by other factors.
1. First, the sample solution to be tested
For example, in the textile industry, the same electrode contacts different test solutions. Some test solutions are single and non-polluting. For example, in general textiles, some test solutions have strong acid and alkali or fluffy and oily solutions, so it is easy to Shorten the service life of the pH electrode. For example, the normal test pH meter can be used for one year, but the frequent test of strong acid and strong alkali pH meter may not work for half a year.
2. The second is the use of time
Long-term non-use or high-frequency use will affect the life of the electrode. For example, some laboratories use it once a day, sometimes even for a few days, and some use it non-stop every day. Then the pH meter that is frequently used every day or that is not frequently used may have a short life. Reasonable use of pH electrodes that are not idle is the best way to extend life.
3. The third is whether you choose the wrong model
If the electrode is found to be inaccurate within a few days of use, it may be that the electrode model is selected incorrectly or the user has improperly used it. Even if the frequency of use is very low, the supplier is not responsible for the return or replacement of the product in this case.
Another situation is that the pH electrode is broken shortly after use or the test is inaccurate, the data is unstable, and the electrode is often used, the appearance is well maintained, and the usual maintenance is strictly in accordance with the instructions, then it may be the electrode. For quality problems, the supplier should be responsible for the return.
The general use time of an electrode is half a year to one year, and the time of industrial pH electrodes with poor use conditions may be shorter.
