- Multi-Parameter Sensing: Measures up to 12 parameters from 6 sensors, including conductivity, pH, ORP, dissolved oxygen (RDO), temperature, water level, and pressure; also provides derived parameters like salinity, TDS, and resistivity
- Rugged & Compact Design: Built for harsh conditions and long-term deployments, reducing field trips and training costs
- Optical RDO®: Patented optical dissolved oxygen sensors with smart caps for easy calibration
- Factory Calibration: Sensors calibrated at the factory for linearity across their full range, simplifying user calibration
- Open Communication: Supports Modbus/RS485 and SDI-12 for integration with telemetry, SCADA, and data loggers
- VuSitu Mobile App: Enables setup, calibration, diagnostics, and real-time data viewing on smartphones/tablets, with alerts
- Versatile Power: Operates on 8–36 VDC, no internal battery required, can power external devices like samplers
- Expandable: Can pair with another instrument via cable splitter for double the sensors
Aqua TROLL 400 Multiparameter Probe
The Aqua TROLL 400 simplifies decision making with a fixed set of sensors that measure:
- Actual and specific conductivity, salinity, total dissolved solids, resistivity and density
- Dissolved oxygen (optical RDO®)
- ORP
- pH
- Temperature
- Water level and water pressure (absolute)
Rugged and compact, the Aqua TROLL 400 can be deployed for months of unattended operation in harsh field conditions. And because it’s easy to install and maintain, you save on training and reduced trips to the field.
Open communication protocols easily interface with your existing telemetry system. Access data anytime with a radio, controller, data logger, sampler, telemetry system, SCADA/PLC system, or HydroVu Data Services.
