Factors affecting the service life of industrial online ph meter electrode
The quality guarantee period of industrial online ph meter electrode is one year on the premise that it has not been used, so many people generally say that the service life of industrial online ph meter electrode is one year, which is actually wrong, because there is a problem of use and maintenance besides the quality of industrial online ph meter electrode itself. The following factors affect the service life of industrial online ph meter electrodes:
1. Media used: The same industrial online ph meter electrode will contact with different media, some of which are clean, such as tap water, and some are strong acid and alkali or even high temperature.
2, use time: some are used occasionally, some are used continuously for a long time.
3, whether cleaning and maintenance, so there will be a big difference, generally speaking, if a ph meter electrode fails in a very short time, it may be that the ph meter electrode model is wrong or the user is not properly maintained. In this case, the general manufacturer is not responsible for returning compensation. Of course, if the industrial online ph meter electrode has been used, but the appearance is still very good, and there is no trace of * * use, it may be the quality of the ph meter electrode, and the manufacturer will generally be responsible for returning the compensation. As for some industrial online ph meter electrodes, they are said to be long-life electrodes, but there are actually some problems.
The general service time of industrial online ph meter electrode is six months to one year, and the service time of industrial online ph meter electrode with poor conditions may be shorter.
How to effectively maintain the acidity meter /PH meter
1. When measuring, the lead-in wire of the electrode should be kept still, otherwise the measurement will be unstable.
2. The power supply used by the instrument should be well grounded.
3. The instrument adopts MOS integrated circuit, so the circuit iron should be well grounded during maintenance.
4. When calibrating the instrument with buffer solution, it is necessary to ensure the reliability of the buffer solution, and the buffer solution cannot be mismatched, otherwise the measurement result will be wrong.
5. The input end of the instrument must be kept dry and clean. When the instrument is not in use, insert the Q9 short-circuit plug into the socket to prevent dust and water vapor from entering.
6. The electrode converter is specially designed for use when other electrodes are used. Pay attention to moisture and dust prevention at ordinary times.
