Calibration method and steps of ph meter
The electrode is the core component of the online PH meter, which is very important. If the electrode fails or cannot be used normally, the entire online PH meter will basically fail to work, so the health of the electrode means the health of the entire device. The service life of the pH meter is also equal to the service life of the pH meter. So how long is the life of the electrode and what factors affect it?
According to statistics, if an electrode is in normal use, the cycle is about one year, but this does not mean that the electrode of an online pH meter must be used for one year, or it will be scrapped after one year, there are many factors that will shorten Or prolong its service life. One year is just an average, depending on how you use it.
Some online pH meters will be exposed to corrosive media such as acid and alkali. If no good measures are taken, it may cause damage to the components, and some high temperature conditions will also damage the equipment, resulting in shortened electrode life. There is also the time and frequency of use. The more you use, the faster the natural wear and tear will be, and the life will be shortened.
In addition, the quality of the pH meter electrode itself is also a prerequisite. In order to reduce costs, some companies purchase products produced by small manufacturers. Although the appearance looks the same as the genuine product, the quality is much worse and the lifespan is not long. Not only the failure rate is high, but also the equipment will be damaged and the production efficiency will be affected.
In addition to the above factors, the maintenance of the electrode of the online pH meter is also indispensable. Even if the electrode is of the best quality, if it lacks maintenance, it will speed up the consumption. The part in contact with the medium should be cleaned frequently to avoid long-term contact with corrosive substances. Equipment, take good care of the equipment, and carry out regular maintenance. You can ask for professional help when performing these operations.
