PH计, 电导率仪, 溶解氧计是用来测量不同水质参数的仪器, and there are obvious differences in their measurement objects, working principles, and application fields.

pH meter
A pH meter is an instrument used to measure the acid-base properties of a solution. It is based on the relationship between the glass electrode and the concentration of hydrogen ions in the solution, and the pH value of the solution is determined by measuring the potential difference of the solution. pH meter is widely used in environmental monitoring, 水质分析, biological science, chemical experiments and other fields, used to measure the pH of the solution, judge the degree of acidity or alkalinity of the solution.

Electrical conductivity meter
Conductivity meter An instrument used to measure the electrical conductivity of ions in a liquid (aqueous solution) or solution. It makes a measurement based on the ability of ions in solution to conduct current and converts it into a conductivity value. Conductivity meters are widely used in water quality analysis, 环境监测, industrial process control and other fields to evaluate the ion concentration, 纯度, dissolved substance content and other indicators of solutions.

Dissolved oxygen meter
The dissolved oxygen meter is used to measure the content of dissolved oxygen in water. It is based on the REDOX reaction between oxygen electrodes and dissolved oxygen in solution, and the concentration of dissolved oxygen in solution is determined by measuring the potential difference. Dissolved oxygen meter is widely used in water quality monitoring, water treatment, aquaculture and other fields, used to evaluate the content of dissolved oxygen in water, judge the REDOX state of water and water quality.

总之, the pH meter is used to measure acid-base properties, the conductivity meter is used to measure ionic conductivity, and the dissolved oxygen meter is used to measure dissolved oxygen content. They differ in measurement principles, application fields and measurement objects, and each is suitable for different water quality parameter analysis and monitoring needs
