Do you know what buffer solutions are used in pH water quality testers?

As we all know, during the use of water quality analyzers, contaminants in the sample water can affect the instrument’s performance. Therefore, after a period of operation, it is necessary to clean and calibrate the equipment to ensure the accuracy of water quality measurements; however, certain challenges may arise during calibration and cleaning.

The online water quality monitoring system safeguards the source of life for you.

China’s water resources are extremely unevenly distributed, with severe regional water shortages. As a result, inter-basin water-transfer projects have proliferated, and the Three Gorges Project and large-scale development initiatives in the western region have placed increasingly stringent demands on water-quality monitoring. In recent years, with the continuous advancement of modern communication technologies and the Internet of Things (IoT), IoT‑based terminal control has found growing application in water-quality monitoring systems.

River Flow Monitoring: What You Need to Know

With the widespread adoption of the “river‑length system,” governments are placing increasing emphasis on monitoring both urban and natural rivers. In particular, river‑flow data provide valuable insights into the health of riparian ecosystems and upstream–downstream ecological networks. What key considerations should be taken into account when conducting river‑flow monitoring?
