AquaTROLL 400 Sonde

Fixed sensor layout for simplified water quality and level monitoring applications.

The Aqua TROLL 400 is a compact multiparameter instrument designed to simplify water quality and level monitoring with a fixed sensor configuration. It measures conductivity, salinity, TDS, resistivity, density, optical dissolved oxygen, ORP, pH, temperature, water level, and absolute pressure in one rugged field-ready device.

 

Built for long-term unattended deployment, the Aqua TROLL 400 performs reliably in harsh environmental conditions while remaining easy to install, operate, and maintain. With open communication protocols, it integrates smoothly with telemetry systems, SCADA/PLC platforms, data loggers, samplers, and HydroVu Data Services.
