Conductivity measurements can be used to characterize water quality changes relative to a baseline or to estimate the concentration of contaminants. Aqua TROLL^® instruments simplify 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.
