BaroTROLL Instrument
The titanium BaroTROLL measures and logs barometric pressure and temperature.
Use the BaroTROLL in conjunction with non-vented In-Situ Instruments.
Win-Situ BaroMerge Software simplifies post-correction of water level data by
automatically subtracting barometric readings from data collected by a non-vented
instrument to compensate for changes in pressure due to barometric fluctuations.
