The NEW Aqua TROLL® 200, the first in a new line of water quality instruments from In-Situ® Inc., monitors and logs conductivity, level/pressure and temperature in the harshest environments. Designed to combat fouling and conserve power, the Aqua TROLL® 200 is built to extend deployment. Power on external 8-36 VDC or internal batteries that are guaranteed for 5 years when logging in 15 minute intervals. Ultra-rugged, corrosion-resistant, titanium construction and small, 0.72” (18.3 mm) diameter make the Aqua TROLL® 200 ideal for demanding marine, surface and ground water 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.
Select between gauged and absolute models with ranges up to 500 psi. All feature a 4MB 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/sec.
Installation and data acquisition is simplified using In-Situ® RuggedCable™ and powerful Win-Situ® software. Use the durable RuggedReader® handheld PC for fast instrument set-up and downloading in the field. Applications
• Saltwater Intrusion Projects
• Tide Gauge Monitoring
• Wetlands Applications
• Ground Water Monitoring
• Estuary Projects
• Surface Water Monitoring
• Discharge Monitoring
• Landslide Prediction
• Aquifer Storage and Recovery |
