Measurement Instrument - Aqua Troll 200

Conductivity measurements can be used to characterize water quality changes relative to a baseline or to estimate the concentration of contaminants.

The Aqua TROLL 200 instrument measures and logs conductivity, temperature, and water level/pressure.
Conductivity measurements can be used to characterize water quality changes relative to a baseline or to estimate the concentration of contaminants.

Rugged Design

Titanium housing safeguards against corrosion.
Sealed to withstand pressures up to 500 psi.

Extended Deployments

Internal batteries guaranteed to last for five years when reading every 15 minutes. External batteries, solar power, or external 8-36 VDC options are also available.
TROLL® Shield antifouling system reduces biofouling and increases deployment times.

Accurate Results

• Dynamic density compensation delivers superior water level accuracy in environments where salinity values vary due to mixing, rainfall, or tides.
• Instruments are factory-calibrated and validated with NIST®-traceable standards.
• Flexible Communications
• SCADA and telemetry-ready units include built-in Modbus/RS485, SDI-12, and 4-21 mA output.
• Easily connects to RuggedReader® handheld PC, laptop, or TROLL® Link telemetry system.

Simplified Setup and Data Acquisition

Win-Situ® software simplifies setup and automates site management.
Standard logging modes include linear, linear average, and event testing1 with logging rates2 as fast as 1/sec.

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

1. External power supply or battery pack required when using event testing and is recommended when using linear average testing.
2. See specifications for specific logging rates using linear, linear average, and event testing.
