In-Situ Aqua TROLL 200

Conductivity + Level + Temp

Data Logger

Conductivity measurements can be used to characterize

water quality changes relative to a baseline or to estimate the

concentration of contaminants. Aqua TROLL® instruments simplify

groundwater and surface water monitoring.

Two models available:

• AquaTROLL®100—Measuresandlogsconductivityand

temperature.

• AquaTROLL®200—Measuresandlogsconductivity,waterlevel/

pressure, and temperature. Dynamic density compensation

delivers superior water level accuracy.
