Year 1978 is important to China as we start economic reform at this year, through the excessive use of resources,China get the rapid development of the economy. but it also created a very severe environment problem.The most obvious aspects of water pollution, such as: water pollution, industrial waste water, medical waste water, river pollution, heavy metal pollution, drinking water problem, domestic sewage and so on. These problem of water environment have seriously affected our lives;at the beginning,customers have no many options in water quality analyzers, mainly use some foreign brands in the domestic market, such as HACH, E+H, METTLER TOLEDO, etc.

Components: Water sensors typically consist of probes, circuits, and an alarm system. Probes come in direct contact with the water, activating the sensor. The circuits analyze the changes in conductivity, capacitance, or light patterns caused by water contact. Once triggered, the alarm system alerts users through sound, light, or notifications, depending on the sensor’s design. Applications: Home Security: Water sensors are integral to home security systems, detecting leaks in basements, bathrooms, or near appliances like washing machines and dishwashers. Industrial Use: Water sensors monitor pipelines in industrial settings, ensuring early detection of leaks that could cause significant damage or production halts. Environmental Monitoring: They also detect reservoir water levels, preventing overflow or depletion.

About industrial production, largely pulp and paper and textile industries, color is often measured in the wastewater for removal purposes and effluent monitoring. Dyes and coloured organic substances are used extensively to add colour to various different substrates in the manufacturing process.
