The BaroTROLL measures and logs barometric pressure and temperature so you can compensate non-vented (absolute) Level TROLL water level data for barometric fluctuations after the fact. Titanium construction and internal power give it the same durability and multi-year deployment life as the rest of the Level TROLL line.

Pair it with In-Situ's BaroMerge software (accessible from HydroVu) to automatically post-correct water level measurements — the software uses the BaroTROLL's log file to correct individual level sensor readings logged during the same time period, and can post-correct multiple data logger files from a single BaroTROLL. Sub-1-inch construction fits smaller-diameter wells, and it connects to telemetry for real-time data and alerts.

Range: 1.14 bar (16.5 psi)
