In-situ On-line Five Nutrient Monitoring Nutritive Salt Analyzer
Nutritive Salt Analyzer
Frankstar Nutritive Salt Analyzer is our core independent R&D achievement. The instrument fully simulates laboratory manual chemical analysis processes. One single analyzer can achieve high-precision in-situ online monitoring of five nutritive salt indicators, including nitrite nitrogen (NO₂-N), nitrate nitrogen (NO₃-N), phosphate (PO₄-P), ammonia nitrogen (NH₄-N) and silicate (SiO₃-Si). Equipped with a supporting handheld debugging terminal, it simplifies parameter configuration and greatly improves operation convenience. This water quality analyzer can be flexibly installed on ocean buoys, survey vessels, shore monitoring stations and other marine observation platforms.
