Conductivity measurements can be used to characterize water quality changes relative to a baseline or to estimate the concentration of contaminants. Aqua TROLL® instruments enhance groundwater and surface water monitoring.
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.
Built-in Modbus/RS485, SDI-12, and 4-20 mA simplify SCADA and telemetry system integration.
Uses Win-Situ® software platform.
Titanium housing safeguards against corrosion.
Batteries last a minimum of 5 years when reading every 15 minutes—guaranteed.
TROLL® Shield antifouling system significantly reduces biofouling.
