In-Situ Aqua TROLL 600 Multiparameter Sonde

The Aqua TROLL 600 is a customizable, powerful multiparameter sonde. It combines industry-leading water quality sensors with revolutionary smartphone mobility, allowing you the ability to collect and analyze data using the VuSitu Mobile App on your mobile device. Rugged in groundwater and corrosion-resistant in surface water, the Aqua TROLL 600 delivers accurate data in an easy-to-use, customizable instrument. Features include a quick-read LCD status screen for visual indicators of overall readiness, battery life, internal log, and sensor status, as well as integrated Bluetooth® connection for wireless data access, and an onboard micro SD card for data backup and download.

Low power consumption with 9+ months of battery life, and advanced antifouling to protect all sensors, make it perfect for challenging environments and long-term deployments in fresh and salt water applications. The Aqua TROLL 600 features self-compensating turbidity, optical RDO, and level, and comes in vented and non-vented options. It is the only multiparameter sonde to have a sub-2 inch passive and active antifouling system for all sensors, including conductivity. Every detail has been engineered for maximum accuracy and minimum hassle. This flexible, data-ready sonde easily integrates with telemetry systems and our new HydroVu Data Services platform for real-time feedback on all your remote water monitoring sites. Access to your data has never been this easy.

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 600 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.

Telemetry2U Compatible

Telemetry2U lets you monitor your sensors, control devices and automate tasks – all through one simple, secure, and configurable IoT platform. In Situ sensors are completely compatible with their technology, allowing for:

  • – Real-time data access on any device
  • – Alerts and alarms for parameters you define
  • – 4G compatibility, allowing you to view live data from even remotely deployed sensors
  • –  Comprehensive reporting and historic data visualizations
