Aqua Troll 200 water quality instrument
The Aqua Troll 200 is the first in a new line of water quality instruments from In-Situ Inc.
It monitors and logs conductivity, level/pressure and temperature in the harshest environments. Designed to combat fouling and conserve power, the instrument is built to extend deployment. It is powered on external 8-36 VDC or internal batteries.
The device is rugged, corrosion resistant, of titanium construction and has an 18.3 mm diameter, making it suitable for demanding marine, surface and groundwater applications. It is SCADA and telemetry capable. Standard outputs include Modbus/RS485, SDI-12 and 4-20 mA.
Users can select between gauged and absolute models with ranges up to 500 psi. All models feature a 4 MB memory that stores up to 200,000 data points. Standard logging modes include linear, fast linear, linear average and event testing with sampling rates as fast as 1/s.
Applications of the device include: saltwater intrusion projects; tide gauge monitoring; wetlands applications; ground water monitoring; estuary projects; surface water monitoring; discharge monitoring; landslide prediction; aquifer storage and recovery.
