Baro TROLL Data Logger

Records barometric pressure to compensate for changes in water level due to barometric fluctuations.

The 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) Aqua TROLL 100/200 or Level TROLL 400/700 water level loggers, or use it with vented systems to calculate barometric efficiency. Baro Merge software handles the rest, automatically post-correcting water level measurements for you.
