Water temperature, conductivity PH、 Online monitoring equipment for dissolved oxygen, ammonia nitrogen, and turbidity

In the field of water environment monitoring, 【 JD-QSZ06 】 water temperature, conductivity PH、 The online monitoring equipment for dissolved oxygen, ammonia nitrogen, and turbidity plays a crucial role in obtaining real-time and accurate data on key indicators of water bodies, providing strong support for water resource protection, water pollution prevention, and other work.

Water temperature online monitoring equipment: sensing changes in water temperature through temperature sensors. Common thermistor sensors utilize the characteristic of resistance changing with temperature to convert temperature signals into electrical signals for measurement. It can quickly respond to fluctuations in water temperature and is widely used for temperature monitoring of water bodies such as rivers, lakes, reservoirs, and industrial wastewater discharge outlets, providing basic data for studying water ecosystems, water conservancy engineering impacts, and more.

Conductivity online monitoring equipment: works based on the principle that the conductivity of the solution is related to the ion concentration. Two electrodes are placed in water, and the conductivity is calculated by measuring the resistance between the two poles and converting it. It can reflect the content of dissolved salts and electrolytes in water, and is used to determine the degree of water pollution and monitor water quality changes in industrial production processes. It is one of the important parameters for water quality monitoring.

PH online monitoring equipment: using the glass electrode method, the glass electrode and reference electrode form a battery, and the potential difference changes with the concentration of hydrogen ions in the solution, thus measuring the pH. This device can monitor the acidity and alkalinity of water bodies in real time, which is of great significance for monitoring the impact of industrial wastewater discharge and soil acidification on water bodies, ensuring that the acidity and alkalinity of water bodies are maintained within an appropriate range.

Dissolved oxygen online monitoring equipment: commonly used are polarographic and fluorescence methods. The polarographic formula applies a certain voltage to the electrode, causing a reduction reaction of dissolved oxygen on the electrode and generating an electric current. The magnitude of the electric current is proportional to the concentration of dissolved oxygen. Fluorescence method uses the interaction between fluorescent substances and dissolved oxygen to measure changes in fluorescence intensity. It is used to evaluate the self purification capacity of water bodies, ensure the survival of aquatic organisms, and is crucial for fields such as fisheries, aquaculture, and sewage treatment.

Ammonia nitrogen online monitoring equipment: mostly using colorimetric or electrode methods. The colorimetric method generates colored compounds by reacting ammonia nitrogen with specific reagents, and determines the ammonia nitrogen content based on the depth of color. The electrode method utilizes an ammonia sensitive electrode to measure the selective response of ammonia nitrogen. Timely monitoring of ammonia nitrogen concentration in water bodies to prevent eutrophication is one of the key indicators for monitoring water environmental quality.

Turbidity online monitoring equipment: Based on the principle of light scattering, when light passes through a water sample, suspended particles in the water scatter the light, and the turbidity is determined by detecting the intensity of the scattered light. It can quickly reflect the content of suspended impurities in water bodies and is used for monitoring the clarity of water quality in drinking water plants, sewage treatment plants, etc.
