The Aqua TROLL 800 fully customizable, seven-port multiparameter sonde, with capacity for six interchangeable sensors and an antifouling wiper, is ideal for short-term or long-term deployments in fresh water or saltwater, surface water or groundwater. The Aqua TROLL 800 features long-lasting battery power and a smartphone interface that enables simplified calibration, live time-series data view and report creation. Vented and non-vented pressure sensor options available.
The Aqua TROLL 800 is designed for optimal accuracy and reliability. In addition to fast-response sensors, built-in error prevention and active and passive antifouling, the Aqua TROLL 800 includes internal logging capabilities and uses two alkaline D batteries for continuous deployment without external power. A micro SD card records backup logs to safeguard your data.
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 800 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
• 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 800 uses only 100 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.
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.
