The Level TROLL 500 is In-Situ’s most popular water level data logger. A cost-effective option suited to a wide variety of projects, the Level TROLL 500 logs continuous measurements of water level, water pressure, and temperature. Titanium construction offers durability and long-lasting performance in fresh or saline groundwater environments. Available in vented (gauged) pressure ranges up to 1153 ft (351 m). Integrate with telemetry systems and HydroVu Data Services for real-time feedback on all of your water monitoring sites.


  • Sub-1 inch diameter
  • Vented (gauged) pressure measurement for automatic atmospheric compensation
  • Fully sealed, all titanium construction and sensors
  • NIST calibration report
  • Flexible native communication protocols (4-20 mA, SDI-12, RS-485)
  • Customizable Rugged Twist-lock Kevlar woven cable (sold separately) suitable for use in high solvents


  • Use data immediately – Vented configuration doesn’t require corrections for barometric pressure changes.
  • 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 – User-friendly software minimizes setup time, with special logging modes for groundwater applications and automated graphing, reports and data export.
  • Reduce field time – Low-power loggers last 10+ years.
  • Quick and easy data-sharing – View and share data on the spot using your mobile device. Intuitive VuSitu Mobile App is an all-in-one software package that provides auto-configuration, simplified calibration, directed data analysis, and automated report creation.
