Introduction and Classification of PH Meter
The PH meter is a commonly used instrument and equipment, mainly used to precisely measure the pH value of the liquid medium. It can also measure the MV value of the ion electrode potential with the corresponding ion selective electrode. It is widely used in industry, agriculture, scientific research, environmental protection and other fields.
Classification of pH meter
According to the needs of production and life, people have scientifically researched and produced many types of pH meters:
According to the measurement accuracy, it can be divided into 0.2 level, 0.1 level, 0.01 level or higher precision.
According to the size of the instrument, there are pen type (mini type), portable type, desktop type and online type for continuous monitoring and measurement.
According to the requirements of use:
Pen type (miniature) and portable PH pH meters are generally used by inspectors to bring them to the site for inspection.
The accuracy level of the pH meter is selected according to the accuracy required by the user for measurement, and then various shapes of pH meters are selected according to the convenience of the user.
Conclusion:
The research and development of PH pH meter in foreign countries was carried out at the beginning of the last century, and China also began to research and produce it in the middle of the last century. In the past two decades, the PH pH meter has developed rapidly, and it can meet people's needs in terms of quality and versatility.
At present, with the use and research of pH meter and the continuous development of science and technology, the electrodes and instruments of pH meter will have great development. It will aim at more accurate measurement and more convenient use. Growing.
