Level TROLL 700 Data Logger
The Level TROLL 700 is In-Situ’s premier water level data logger, giving groundwater professionals higher data resolution, expanded memory and advanced logging modes for specialized applications. Designed specifically for aquifer characterization, the Level TROLL 700 provides continuous monitoring of water level, water pressure, and temperature. Titanium construction means long-lasting performance in fresh, saline and even contaminated environments, with low-power batteries that last 10 years or more.
Available in pressure ranges up to 1153 ft (351 m) for vented configurations and 2274 ft (693 m) for non-vented configurations. Get real-time data via direct-read RuggedCable, or download data periodically. Integrate with telemetry systems and HydroVu Data Services for real-time feedback on all of your water monitoring sites.
