Rugged BaroTROLL Data Logger


The Rugged BaroTROLL Data Logger measures and logs barometric pressure and temperature, data needed to compensate for water level changes due to barometric fluctuations. Use this data logger with non-vented (absolute) Rugged TROLL 100 or 200 water level loggers. Baro Merge Software does the rest for you, automatically correcting water level data for barometric pressure changes.
