In-Situ Aqua Troll® 100

Conductivity, Temperature, Plus Water Level Logging


Conductivity measurements can be used to characterize water quality changes relative to a baseline or to estimate the concentration of contaminants. The In-Situ® Aqua TROLL 100 Instruments measure and log conductivity and temperature.

Rugged, Compact Design

  • Use in harsh environments. Titanium construction resists fouling and is chemical- and corrosion-resistant.
  • Deploy 1.83-cm (0.72-in) diameter instruments into narrow wells.

Extended Deployments

  • Reduce power consumption. Batteries have a typical life of 5 years when reading every 15 minutes. 8-36 VDC input is compatible with external batteries and solar power.
  • Use the TROLL® Shield Antifouling System to reduce biofouling and extend deployments by up to 6 weeks.

Accurate Results

  • Use dynamic density compensation to collect accurate water level data in environments where salinity values may vary.
  • Receive factory-calibrated instruments that are validated with NIST®-traceable standards.
  • Deploy for long-term monitoring. Instruments operate with very low drift.

Flexible Communications

  • Integrate into telemetry and SCADA systems. Outputs include standard Modbus/RS485, SDI-12, and 4-20 mA.
  • Easily connect to RuggedReader® Handheld PC or PC.
  • Use RuggedCable® Systems with titanium twist-lock connectors for quick, reliable connections.
  • Simplify instrument setup, automate site management, and view real-time results with Win-Situ® Software.
