Shanghai online ph meter

With the upgrading of China's automation industry in recent years, more and more workplaces that were originally human have been handed over to automated instrumentation. Compared with people, automated instruments are 'not exhausted　　Shanghai online pH meter, I believe it is a product that is familiar to the customers who use it for online pH measurement in Shanghai. The pH meter product, the earliest birthplace in China, is actually Shanghai. However, with the development of technology and the increase in demand from other domestic industrial belts, many online pH meter brands have emerged throughout the country, relying on high-quality products and professional technology to meet the needs of local customers. Therefore, if you want to understand or buy, you can look across the country instead of just confining to Shanghai. Before that, you must know something about this product yourself.　　 is the principle first. The online pH meter works on the principle of a galvanic cell. The electromotive force between the two electrodes of the galvanic cell is based on Nerns's law, which is not only related to the electrode's own properties, but also to the concentration of hydrogen ions in the solution. There is a corresponding relationship between the electromotive force of the primary battery and the hydrogen ion concentration, and the negative logarithm of the hydrogen ion concentration is the pH value.　　 is followed by application occasions. The online pH meter is one of the intelligent online chemical analysis instruments, which is widely used in continuous monitoring of the pH value in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemicals, food and tap water.　　 Next is the characteristic. The online pH meter has the following advantages.　　1. First of all, the online pH meter replaces the original manual periodic measurement. It can monitor the pH value of the current solution in real time, and can be connected to a control or recording device for action control or record real-time pH value.　　2. The online ph meter can not only record the ph value, but also record the orp value, temperature value, and simultaneously perform upper and lower limit control, 4-20mA transmission output, or RS485 communication function.　　3. There is an industrial control watchdog to ensure that the instrument will not crash.　　4, has good waterproof and moisture-proof performance　　Finally, there are parameters and selection. The first is the pH measurement range. Generally, the measurement range of 0-14 is common in the market, but some of the rarer ones are the range of 2-12, or the large range of -2-16.　　 Next is the accuracy requirement. Generally, the online pH meter on the market has an accuracy of 0.02PH and a resolution of 0.01PH. In terms of transmission output, the general products on the market will have 4-20mA output, and some manufacturers' products can do RS485 communication. Then there is power supply. Generally, the common 220V power supply on the market is used for power supply, but some manufacturers can also provide 24V power supply, which is more convenient in some industrial occasions. Finally, the relay is a very important module for pH control. Generally, there are two sets of relay outputs, so that the control of adding acid or alkali can be carried out.　　To sum up, it is the principle, application, characteristics, and parameter selection of the online pH meter. I believe that after reading it, you must have a general understanding of the online pH meter, right? There are more online pH meters on the market, the MIK series of online pH meters. If you want to know or purchase, you are recommended to look for this series directly. Yes, it has basic models, upgraded models, high-end models, wall-mounted models, etc. I believe there will be something that meets your requirements.
