In-Situ Nutrient Sensor
Frankstar in-situ nutrient sensor adapts established wet-chemistry methods into a fully automated, in-situ nutrient analyzer. The instrument strictly follows national standard detection protocols and accurately replicates manual laboratory procedures. Using precise reagent handling and automated reaction control, a single In-Situ Nutrient Sensor can simultaneously and continuously measure up to five key nutrients: nitrite (NO₂-N), nitrate (NO₃-N), phosphate (PO₄-P), ammonia nitrogen (NH₄-N), and silicate (SiO₃-Si).

Aramid Fiber Rope
Engineered for the marine environment, this line combines an aramid-fiber core with a polyamide-fiber outer construction. A low-helix-angle braid and pre-stabilized construction minimize break elongation, ensuring stable station-keeping. The high-density surface weave maximizes abrasion resistance, while a dual-color identification system simplifies sub-sea installation. Multi-layer reinforcement withstands extreme sea-state impacts, making the line ideal for high-load applications such as subsurface buoy and mooring-anchor systems.
