The Aqua TROLL 200 is a reliable all-in-one instrument that measures and records water level and pressure, conductivity, and temperature. It is available in vented and non-vented configurations and features a unique conductivity cell design that allows a wide, accurate measurement range in a narrow-diameter instrument.Titanium construction resists corrosion, and the sub-1-inch design fits narrow-diameter wells, making it ideal for coastal, remediation, and mine water monitoring projects. The VuSitu mobile app provides auto-configuration, simplified calibration, directed data analysis, and automated report creation. Open communication protocols integrate with third-party data loggers and telemetry systems, and it works with HydroVu Data Services or direct-read Rugged Cable for real-time data access and automatic event alerts.Why it works 3D factory calibration. Pressure sensors are calibrated across full pressure and full temperature ranges for accuracy at any depth, NIST certified where applicable. Simple data management. Consolidate site information on your smartphone, tag data with photos and GPS, and export standard CSV files. Rugged cable. Kevlar strands prevent stretch and breakage, and titanium twist-lock connectors make quick, reliable connections. Base configuration; cable length and vented or non-vented options are configured at order time. Contact us to spec the right configuration.
