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.
