It features a durable, waterproof (IP68) body, typical range of 0–1000 mg/L, and low maintenance without reagent consumption. Common applications include drinking water safety monitoring (nitrate is regulated due to health risks), aquaculture (toxic to fish), agricultural runoff monitoring, and wastewater denitrification control. By providing real‑time nitrate data, the digital sensor helps optimize treatment processes, reduce chemical usage, ensure regulatory compliance, and protect public health and aquatic ecosystems. Compared to colorimetric analyzers, it requires no chemicals, no sample preparation, and has faster response and lower operating cost, making it essential for unattended, continuous water quality monitoring. -
