DEC790 online Digital Conductivity Sensor developed and produced by DOSZ is widely used in surface water conductivity detection system. This Online Conductivity Sensor uses a PPS shell, which is easy to carry and more corrosion-resistant than stainless steel. Surface water conductivity refers to a measure of the electrolyte content in surface water, which refers the degree of pollution and self-purification ability of the water body. The limit value of conductivity is an important parameter for assessing the environmental quality of surface water and is of great significance for monitoring and protecting water resources.Conductivity is usually expressed in units of μS/cm. High conductivity means that the water contains more electrolytes, such as salts, metal ions, etc. Monitoring surface water conductivity is of great significance for assessing the degree of pollution, self-purification ability of water bodies and the rational utilization of water resources. The construction and operation of surface water conductivity monitoring stations play an important role in ensuring water resource quality and water environment safety.

Measurement principle

The acid, alkali, and salt electrode dissolved in water dissociate positive and negative ions in the solution, making the electrolyte solution conductive. The conductivity can be expressed by conductivity. The conductivity of an electrolyte solution is usually determined by inserting two metal pieces (i.e. electrodes) into the solution and measuring the resistivity between the two electrodes. Conductivity is the reciprocal of resistivity. It is defined as the conductivity of the solution when the cross-sectional area is 1 square centimeter and the inter-electrode distance is 1cm.

The standard for water quality testing conductivity will also be affected by seasonal and regional factors. Since water quality characteristics vary in different seasons and regions, the impact of these factors on conductivity standards needs to be considered when conducting water quality testing. For example, the concentration of dissolved substances in water will change during the rainy and dry seasons, so the conductivity standards will also be different.

The conductivity value of surface water is monitored to assess water quality and the content of dissolved salts and other chemicals in the water body. Conductivity is a measure of the concentration of electrolytes in a body of water. High conductivity usually means there is a higher level of salt or other dissolved substances in the water, which can affect water quality and the health of ecosystem. Therefore, monitoring the conductivity value of surface water can helo us understand the degree of pollution of water bodies and take necessary measures in time to protect water resources and the ecological environment.
