SKU 0096400

The Aqua TROLL 600 is a fully customizable multiparameter sonde with interchangeable sensors, long-lasting battery power, and a smartphone interface that delivers accurate data and enables simplified calibration, panoramic data view, and report creation. Ideal for short-term and long-term deployment. Available in vented and non-vented options.

The Aqua TROLL 600 is designed for optimal accuracy and reliability. Check the Onboard LCD screen for overall readiness, battery life, internal log, and sensor status. The Aqua TROLL 600 has a wiper port and 4 smart sensor ports enabling end-user configuration of the sensing parameters.

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.


Shared Ecosystem

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.

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 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.

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.
