Aqua TROLL 100 And 200 Instruments

Conductivity measurements can be used to characterize water quality changes relative to a baseline or to estimate the concentration of contaminants. Aqua TROLL® instruments enhance groundwater and surface water monitoring.

• Aqua TROLL® 100 — Measures and logs conductivity and temperature.
• Aqua TROLL® 200 — Measures and logs conductivity, water level/pressure, and temperature. Dynamic density compensation delivers superior water level accuracy.

Flexible Communications

• Built-in Modbus/RS485, SDI-12, and 4-20 mA simplify SCADA and telemetry system integration.
• Uses Win-Situ® software platform.

Extended Deployments

• Titanium housing safeguards against corrosion.
• Batteries last a minimum of 5 years when reading every 15 minutes—guaranteed.
• TROLL® Shield antifouling system significantly reduces biofouling.

Applications

• Aquifer storage and recovery
• Discharge monitoring
• Estuary and wetland studies
• Mine water management
• Recovery water monitoring at hydraulic fracturing sites
• Remediation projects
• Saltwater intrusion monitoring
• Storm surge analysis
• Tracer studies
