Overview: The Aqua TROLL 100 and 200 are instruments designed for measuring and logging conductivity, temperature, and water level/pressure (Aqua TROLL 200 only) to monitor water quality changes and estimate contaminant concentrations. They feature a four-electrode conductivity cell that minimizes fouling and electrical interference, housed in durable titanium for corrosion resistance.
Specifications:- Temperature Range: Operational from -20° to 65°C; storage from -40° to 65°C.
- Dimensions: Diameter of 0.72 inches and length of 12.4 inches.
- Pressure Range: Operates from 0 to 500 psi.
- Power: Internal battery life of 5 years or 200,000 readings; external power options available.
- Logging: Memory capacity of 4MB for 380,000 data points; supports linear, linear average, and event log types.
- Temperature Accuracy: ±0.1°C with a resolution of 0.1°C.
- Conductivity Range: 5 µS/cm to 100,000 µS/cm with varying accuracy based on range.
- Pressure/Level Measurement: Available only in Aqua TROLL 200, with various non-vented and vented ranges.
Features:- Rugged Design: Titanium housing resists fouling and corrosion.
- Extended Deployments: Internal and external power options, with antifouling systems to extend deployment time.
- Accurate Results: Dynamic density compensation for accurate water level readings in variable salinity environments.
- Flexible Communications: Supports Modbus/RS485, SDI-12, and 4-20 mA outputs.
- Simplified Setup: Win-Situ software for easy setup and data management.
Applications: Suitable for aquifer storage, saline aquifer studies, discharge monitoring, estuary studies, irrigation, mine water analysis, remediation, salt runoff studies, saltwater intrusion monitoring, storm surge analysis, surface water testing, tide gauge monitoring, tracer studies, and wetlands restoration.
Antifouling System: The TROLL Shield system combats biofouling, extending deployment by up to 8 weeks with a copper nose cone and guard.
Warranty: One-year warranty for instruments and two years for RuggedCable systems, with extended warranties available.
