The wastewater monitoring equipment PCB is the "sewage quality control core" for industrial and municipal wastewater treatment. Engineered to withstand corrosive, high-moisture environments, it integrates sensors for chemical oxygen demand (COD), biochemical oxygen demand (BOD), suspended solids (SS), and heavy metals. Leveraging our 10000㎡ factory’s advanced testing equipment, it ensures stable data output with anti-fouling and self-cleaning circuit design, supporting online continuous monitoring and data upload to treatment systems. Applied in wastewater treatment plants, industrial discharge outlets, and rivers, helping control water pollution and ensure compliance with discharge standards.
