Seawater Nutrient Analyzer
Catalog NO.: AIMRSE-LAB-SEN-032 Manufacturer PN: LAB-SW-NA
• Multi-optical path coupling technology; compact size for convenient portability and deployment
Measures five dissolved nutrients in seawater: ammonium (NH₄-N), nitrite (NO₂⁻-N), nitrate (NO₃⁻-N), phosphate (PO₄-P), and silicate (Si-SiO₃).
The Nutrient Salt In-Situ Analyzer is a chemical sensor suitable for shallow water environments. It operates on the principle of spectrophotometry, employing fluorescence for ammonia nitrogen measurement. The instrument uses a peristaltic pump and solenoid valve assembly to sequentially inject samples and reagents into a micro-flow circuit for mixing and reaction. After measurement, the flow path is flushed with water samples.
