Aqua TROLL 100 Data Logger


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, ideal for coastal, remediation and mine water monitoring projects. Deploy the Aqua TROLL 100 in depths up to 500 psi (1153 ft; 351.43 m). Get easy data access via telemetry systems and HydroVu Data Services, or direct-read Rugged Cable (sold separately).



  • Sub-1 inch diameter (0.72 in; 1.83 cm)

  • All titanium electrodes and housing

  • Full range conductivity with optimum accuracy – 5 to 100,000 µS/cm

  • Flexible communication protocols (4-20 mA, SDI-12, RS-485)

  • NIST calibration report for guaranteed accuracy

  • Rugged Twist-lock cable (sold separately)



  • Fits your deployment – Compact design fits narrow diameter wells.

  • Protect your data and your equipment – Solid titanium construction outlasts specially coated data loggers, even in harsh environments.

  • Simplify project setup and control – Open communications protocols easily integrate with existing telemetry systems and HydroVu Data Services, plus get 24/7 data and automatic event alerts.

  • Streamline data collection and analysis – Powerful software with special logging modes automates water level corrections, post-processing, report generation and data export.
