Level TROLL 400 Data Logger
The Level TROLL 400 measures and logs water level, water pressure, and temperature in a maintenance-free system ideal for long-term monitoring at flood-prone or high humidity sites. Durable titanium construction guarantees long-lasting performance in fresh or saline groundwater and surface-water environments. Available in non-vented (absolute) pressure ranges up to 1120 ft (341 m). Integrate with telemetry systems and HydroVu Data Services for real-time feedback on all of your water monitoring sites.
