Marine environments are complex. Standard sensors often struggle with salinity interference and spectral overlap, leading to unreliable UV-based nitrate measurements.

🔬 Meet OPUS by TriOS – a hyperspectral photometer featuring Linear Spectral Analysis (LSA), a sophisticated firmware solution that compensates for environmental effects and ensures precise nitrate detection.

🧠 What Is LSA?

LSA (Linear Spectral Analysis) is an advanced firmware integrated into OPUS that enables accurate spectral interpretation—even in challenging water conditions.
Different LSA packages are available, tailored for:

• Seawater
• River water
• Brackish water
• Wastewater treatment plants
• Industrial water

🌊 Trusted in Global Marine Applications, e.g.

• Argo floats for worldwide ocean monitoring
• Great Barrier Reef nutrient tracking (Reef 2050 Plan)
• Coastal and deep-sea research (up to 6000 m depth)

⚙️ Key Features

• Durable titanium housing with SubConn connectors
• Customizable LSA firmware packages
• Automatic cleaning systems for long-term deployments
• Web access, Modbus RTU, and onboard data logging

OPUS brings lab-grade spectral precision into the ocean—where it’s needed most.
