The Aqua TROLL 200 conductivity data logger, water level meter is the first in the range of water quality monitoring instruments from In-Situ Inc. The Aqua TROLL 200 measures conductivity, level/pressure and temperature in the harshest conditions.
The Aqua TROLL 200 is designed to combat fouling and conserve power and is built to extend deployment. Can be powered externally with 8-36 VDC or by internal batteries which are guaranteed to last for 5 years when reading every 15 minutes. The TROLL has a titanium construction, is ultra-rugged, corrosion resistant and 0.72"(18.3mm) diameter make the Aqua TROLL 200 the ideal instrument for demanding marine, surface and groundwater applications.
Building on the successful Level TROLL platform, the Aqua TROLL 200 is SCADA and telemetry ready. Standard outputs include Modbus/RS485, SDI-12 and 4-20 mA.
With a high accuracy pressure sensor, the Aqua TROLL 200 also allows superior water level accuracy in estuary and coastal environments where salinity values vary due to mixing, rainfall or tides by dynamically compensating level readings for changes in water density due to changes in salinity.
Choice of either gauged or absolute models with ranges up to 500psi. All models feature a 4MB memory which can store up to 380,000 data points. Standard logging modes include linear, linear average and event testing with logging rates as fast as 1/sec. Easy to install using an In-Situ Rugged cable. Data acquisition is made easy using Win-Situ software. Rugged Reader is also available for quick instrument set-up and downloading in the field.
