Innovations in Water Monitoring TROLL® 9500 Multiparameter Instrument Logging Models • • The powerful, portable TROLL 9500 Water Quality Instrument is designed for groundwater and surface water monitoring. The unit houses up to nine water quality sensors, internal power, and optional data logger. Lower Total Cost of Ownership • • • Instrument saves time and money by offering long-lasting internal power, automated low-flow sampling, and telemetry accessibility. Field-proven sensors and antifouling system reduce maintenance and site visits. Intuitive Win-Situ® 4 Software and Flow-Sense Software improve efficiency by simplifying data collection and management. LTS: LTS stands for “Level, Temperature, and one additional Sensor,” such as conductivity, dissolved oxygen (DO), or pH. Professional: This unit offers the highest value for most applications. Instrument allows for several sensors, including conductivity/salinity, DO, ORP, pH, temperature, or depth. Professional XP: The most capable TROLL 9500 offers features available on the Professional and supports XP or “Extended Parameter” sensors—turbidity, ammonium, chloride, or nitrate. Non-Logging Models • Profiler: Ideal for sampling or vertical profiling, this unit is similar to the Professional, but does not include memory or logging capabilities. Data can be logged to a RuggedReader® Handheld PC or laptop. Profiler XP: This unit offers the same features as the Profiler with the option to use XP sensors. Reliable, Accurate Operation • • • Instrument operates in fresh, waste, and marine waters. Instrument offers proven performance. Rigorous third-party testing shows that the TROLL 9500 delivers consistent results. Sensors are factory calibrated with NIST®-traceable standards (where applicable). Outstanding Customer Service • • Free, 24/7 technical support Seven-day service for maintenance and calibration (U.S.A. only) Coastal deployments—estuaries and wetlands Environmental monitoring and spot checking Low-flow groundwater sampling Remediation and mine water monitoring Stormwater management Vertical profiling

TROLL® 9500 Water Quality Sensors Customizable for Your Application Choose from several field-ready sensors. The selected sensor set will determine the diameter of the TROLL 9500—sub-2 inch or sub-4 inch. Breakthrough RDO technology surpasses Clark cell performance by eliminating hydration effects, membranes, electrolyte solution, and stirring. • • Barometric pressure: Use this sensor to compensate water level and DO values. • Conductivity: Characterize water quality in actual conductivity, specific conductivity, salinity, TDS, or specific gravity. • DO: Choose from the optical Rugged Dissolved...

Real-Time Monitoring for Remediation Conduct ISCO, ISCR, Biosparging, Air Sparging & More The TROLL® 9500 Instrument supports real-time measurement of performance indicators, which allows for a dynamic work strategy per the EPA Triad Approach to site remediation. You can adapt to changing conditions as new data becomes available. This allows you to complete projects more quickly and at a lower cost than when using traditional approaches. With the TROLL 9500, you can: • Deploy a sub-2 inch instrument and monitor DO with the RDO® Sensor, conductivity, pH/ORP, temperature, and barometric pressure....
