The Aqua TROLL 100 Data Logger measures and records conductivity and temperature. A unique conductivity cell design allows for a wide, accurate measurement range in a narrow diameter instrument. Titanium construction resists corrosion, making the Aqua TROLL 100 Data Logger ideal for coastal, remediation and mine water monitoring projects. Deploy the Aqua TROLL 100 in depths up to 300 psi.

The powerful VuSitu mobile app pairs perfectly to provide auto-configuration, simplified calibration, directed data analysis, and automated report creation.

View and share data on the spot using your mobile device and use open communication protocols to easily integrate with existing SCADA and telemetry systems and HydroVu Data Services for real-time data access and automatic events alerts.


Shared Ecosystem

Reduce complexity and cost with equipment that works together. All Aqua TROLL and Level TROLL products use the same ecosystem—from instrument to cable to communication.

Simple Data Management

Consolidate all site information with the VuSitu mobile app and tag data with site photos and GPS coordinates. Log data to your smartphone and download results in a standard .csv file format.

Rugged Cable

Kevlar strands ensure that our cable won’t stretch or break. Titanium twist-lock connectors enable quick, reliable connections, and Kevlar Grip provides redundant security. Use with the Rugged Cable Splitter to measure multiple parameters at various depths simultaneously.
