The Aqua TROLL 500 is a fully customizable multiparameter sonde with interchangeable sensors and a smartphone interface that delivers accurate data and enables simplified calibration, panoramic data view and report creation. Ideal for spot-checking and profiling applications when used with a Wireless TROLL Com or long-term monitoring with VuLink.
The Aqua TROLL 500 offers the flexibility, reliability and ruggedness you need for spot checking, low-flow sampling, remote monitoring, and long-term water or stormwater monitoring. Corrosion-resistant titainum construction stands up to harsh environments, and a convenient LCD readout of sensor health and connectivity gives you confidence in your deployment.
Sensor options include temperature, pressure, conductivity, pH/ORP, Rugged Dissolved Oxygen (RDO®), turbidity, chlorophyll a, Phycocyanin (BGA-PC), Phycoerythrin (BGA-PE), Rhodamine WT, ammonium (ISE), chloride(ISE) and nitrate (ISE).
Non-Vented Cable, Vented Cable and Wireless TROLL Com sold separately.
Reduce complexity and cost with equipment that works together. All Aqua TROLL products use the same ecosystem—from handheld to cable to communication.
3D Factory Calibration
In-Situ performs a multi-point factory calibration on every sensor. This calibration ensures that the sensor is linear across its full range and reduces the complexity of user calibration.
Low Maintenance Deployment
Keep labor and equipment costs down with advanced sub-2-inch passive and active antifouling on all sensors and 9+ month battery life. The Aqua TROLL 500 is reliable in challenging environments and ideal for long-term deployments in fresh and saltwater.
In-Situ equipment is designed to withstand use in the harshest environments. Features designed to prevent breakage or failure include:
• Interlocking sensors for greater stability
• Titanium restrictor
• Fully potted sensors
• Redundant SD card storage
• Multi-chamber design
Built-In Error Protection
Prevent the most common damage or loss with:
• Spring-loaded screws that keep screws in place
• Slip-clutch wiper to prevent motor damage
• Smart sensors that fit in any port
• Wet-mate connectors that prevent water damage
• Anti-roll bumpers to keep equipment stationary
Mini Calibration Cup
The Aqua TROLL 500 uses only 50 mL of calibration solution for both rinsing and calibration. This feature reduces the calibration cost by 5x over traditional methods, saving thousands of dollars in calibration solution per year.
Aqua TROLL sensors were designed to support spot-checking and profiling applications where sensor response time is critical. The temperature sensor uses extended thermistor and insulated barriers; RDO® has optional fast-response formulation; and a round bulb increases surface area and improves response time on pH sensor.
Monitor dissolved oxygen and control aerator function to protect stocks and increase yields.
Monitor inland or coastal water easily and accurately with equipment designed to work together.
Continuous Groundwater Monitoring
Measure water level and water quality over time at local or regional scales.
Monitor groundwater, surface water and air, both during and after in-situ treatment of contaminated groundwater.
Remotely monitor for harmful algal blooms for quick response and improved trend analysis.
Monitor level, quality and flow continuously to establish baseline parameters and see changes during storm events.
