Aqua TROLL 700 Multiparameter Sonde

The Aqua TROLL 700 is a fully customizable seven-port multiparameter sonde with capacity for six interchangeable sensors plus an antifouling wiper. It offers the flexibility, reliability, and ruggedness required for spot checking, remote monitoring, and long-term monitoring in surface water, coastal, and groundwater applications.

Use it with a TROLL Com Plus and the VuSitu mobile app for spot-checking and profiling, or pair it with VuLink telemetry and HydroVu data services for long-term remote monitoring. Vented and non-vented pressure sensor options are available. Sensor options include temperature, conductivity, pH/ORP, Rugged Dissolved Oxygen (RDO), turbidity, chlorophyll a, phycocyanin (BGA-PC), phycoerythrin (BGA-PE), FDOM, crude oil, rhodamine WT, fluorescein WT, ammonium, chloride, and nitrate.

Why it works

• Six sensors at once. Seven ports run six interchangeable smart sensors plus a wiper, so one instrument covers an entire monitoring program.
• Shared ecosystem. Same handhelds, cables, and telemetry across the Aqua TROLL line.
• 3D factory calibration. Multi-point factory calibration on every sensor for linear response across the full range.
• Low-maintenance deployment. Sub-3-inch mechanical antifouling and 9+ month battery life for long deployments in fresh and saltwater.
• Mini calibration cup. Rinses and calibrates with just 100 mL of solution, cutting calibration cost by more than half.
• Built-in error protection. Spring-loaded screws, slip-clutch wiper, port-agnostic smart sensors, wet-mate connectors, and anti-roll bumpers.
