Level TROLL 400

Level TROLL 400 is for you. This low-maintenance data logger measures and records water level, water pressure, and temperature. Ideal for long-term monitoring in locations prone to flooding or with high humidity, the TROLL Level 400 is available in the non-ventilation (absolute) pressure range.

Our 3D factory calibration and unique anti-drift system ensure accuracy, and the durable titanium construction is designed to withstand harsh conditions in fresh or salt water, in both groundwater and surface water environments. As part of the In-Situ shared ecosystem, this versatile instrument easily integrates with accessories and in-well telemetry.

Pair with VuLink In-Situ telemetry and HydroVu Data Services for powerful remote data access and management. Smart addressing allows you to connect any device to the same data logger without reprogramming it to monitor the same parameters.
