Extend the life of the pH meter
Although there are standard and mature methods for the detection of pH value, its detection methods and methods are still in constant development and change. In the research and development of new technologies, longer service life is the top priority of research and development.
In the past ten years, the glass electrode for pH detection has been rapidly promoted in the market, and a large number of variant products make it difficult for people to make an accurate choice, especially when the use of the glass electrode is close to the limit of use. Dr. Dirk Steinmöller, Head of Marketing at Knick AG, who is currently responsible for the development of pH detection technology, said: "The development of pH detection electrode technology in recent years is the development and progress of real technical details, such as special applications for special occasions. Glass material, etc. From the point of view of hygiene and waste disposal, the development trend of pH detection electrodes is to use lead-free glass tubes. This has been standardized in all products of Knick company, or use free maintain slightly toxic electrodes."
"Powerful, expensive detection electrodes often fail due to simple interchangeable connections." - Dr. Dirk Steinmöller, Knick Corporation
The biggest feature of the new technology is mainly reflected in the reference electrode, because it is the weakest link in the whole pH detection. Mr. Matthias Kremer, head of Jumo's analysis and detection technology product production, clearly pointed out: "In pH detection, more than 80% of the detector damage occurs on the reference electrode." However, through the correct selection of electrode diaphragm, electrode filler (liquid , gel) and the optimization of the mechanical and electrical interfaces can effectively avoid the premature failure of the pH detection electrode.
"Good technical consultation, keeping close contact with users, and providing as much information and data as possible on the detection points are the basis for the correct selection of detection electrodes." -Mr. Mattias Kremer, Jumo Company
However, the pH detection electrode is a wear part, which is affected by temperature, pressure, chemical or mechanical load during use, and its typical service life is several days to several years.
The improvement of Knick's products in this respect is: the improvement of the external structure and performance of the pH detection electrode. For example, the InduCon technical standard developed and used by Knick Company, the plug-in system produced according to this standard uses the supply method to supply power to the pH detection sensor, and can also realize non-contact data information transmission. Mr. Steinmöller said: "This has very important practical significance, and at the same time it can completely rule out common detection problems, such as problems caused by poor contact or corrosion of plug connectors; at the same time, it can also avoid problems caused by Abnormal changes in detection data caused by poor isolation of detection points. This is a huge improvement for users of pH detectors, so that they no longer have to worry about the detection performance of the sensor."
