The Aqua TROLL 700 is a fully customizable, seven-port multiparameter sonde with capacity for six interchangeable sensors and an antifouling wiper. It offers the flexibility, reliability and ruggedness required for spot checking, remote monitoring, and long-term monitoring in surface water, coastal and groundwater applications. A smartphone interface delivers accurate data and enables simplified calibration, live time-series data view and report creation.
Use the Aqua TROLL 700 with a Wireless TROLL Com and the VuSitu mobile app for spot-checking and profiling applications and with VuLink telemetry and HydroVu data services for long-term monitoring.
Interlocking, fast-response sensors, a mini calibration cup onboard and built-in error prevention streamline setup and deployment, while active and passive antifouling features extend intervals between maintenance visits. Vented and non-vented pressure sensor options available.
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-3-inch passive and active antifouling on all sensors and 9+ month battery life. The Aqua TROLL 700 is reliable in challenging environments and ideal for long-term deployments in fresh water and saltwater.
Enhanced Reliability
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
• 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 700 uses only 100 mL of calibration solution for both rinsing and calibration. This feature reduces the calibration cost by over half compared to traditional methods, saving thousands of dollars in calibration solution per year.
Fast-Response Sensors
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.
