Analyseur de nutriments et de désinfectants
Focused Photonics Inc. (FPI) advances aquatic health with its Nutrient and Disinfectant Analyzers, delivering precise, real-time detection of chlorophyll-a, blue-green algae, COD, ions, residual chlorine, and turbidity in lakes, rivers, and treatment plants. The SIA and sensor series employ fluorescence, UV absorbance, ISE, and chemical methods for compliance with ISO 7027, GB 3838-2002, and EPA Method 415.3.
Aquatic Audit: Principles of Nutrient and Disinfectant Detection
Hydrological sensors measure water dynamics using microwave radar, Doppler shift, and hydrostatic pressure for non-invasive level, flow, and velocity profiling. FPI’s sensors employ 26 GHz radar for level (0-30m, ±1 mm accuracy) and flow (0-20 m³/s, ±1%), Doppler for velocity (0-10 m/s, ±0.01 m/s), and hydrostatic transmitters for submerged depth (0-100m, ±0.1%), per ISO 1438.

Evolved from 1980s ultrasonic probes, these sensors integrate AI for wave compensation and low-power operation (-20°C to 60°C). FPI refines with anti-fouling coatings and 4-20 mA outputs, ensuring <0.5% drift per USGS guidelines. In 2025’s flood-resilient era, our networks fuse radar data with IoT for predictive modeling, informing SDG 6 water security.
