Unless you require vented level data, the Level TROLL 400 is for you. This low-maintenance data logger measures and logs water level, water pressure and temperature. Ideal for long-term monitoring at flood-prone or high-humidity sites, the Level TROLL 400 is available in non-vented (absolute) pressure ranges. 3D factory calibration and our unique anti-drift system ensure accuracy, and durable titanium construction is designed to withstand harsh conditions in fresh or saltwater, in either groundwater or surface water environments.
As part of In-Situ's shared ecosystem, this versatile instrument easily integrates with accessories and in-well telemetry. Pair with In-Situ's VuLink telemetry and HydroVu Data Services for powerful remote data access and management. Smart addressing enables you to connect any device to the same data logger without reprogramming to monitor the same parameter.
