Aqua TROLL 100 and 200 Spec Sheet - In-Situ - #1

1

Conductivity measurements can be used to characterize water quality changes relative to a baseline or to estimate^, the concentration of contaminants. The In-Situ® Aqua TROLL 100 and Aqua TROLL 200 instruments measure and log conductivity and temperature. For added flexibility, the Aqua TROLL 200 also measures and records water level/pressure.

The In-Situ four-electrode conductivity cell is less subject to fouling and resists electrical field effects from pumps and well casings. The cell design allows for a wide measurement range with a narrow diameter instrument (0.72 in; 18.3 mm).

I • Durable titanium housing resists fouling and safeguards against corrosion, even itf the harshest conditions.

• Completely sealed—Withstands pressures up to 500 ¿i i= Extended deployments

• Internal batteries guaranteed to last for 5 years when reading every 15 minutes. External batteries, solar power, or external 8-36 VDC options are also available.

• Reference electrode compensates for light fouling.

^ • Use with the TROLL® Shield antifouling system to reduce biofouling and significantly increase deployment time.

t~ Accurate results

§^ • Dynamic density compensation delivers superior water |—-| accuracy in estuarine and coastal environments where salinity values may vary due to rainfall or tides:

• Instruments are factory-calibrated and validated with NIST®-traceable standards.

• SCADA and telemetry-ready units include built-in Modbus/ RS485, SDI-12, and 4-20 mA output communications.

• The In-Situ RuggedCable® system includes titanium Twist-Lock connectors for quick, reliable connections.

• Easily connects to a RuggedReader® handheld PC, laptop, or TROLL® Link telemetry system.

Win-Situ® software simplifies instrument setup, automates site management, displays graphical data, and provides real-time data and instrument status.
