Innovations in Water Monitoring Rugged TROLL® 100 and 200 Data Loggers Rugged TROLL 100 and 200 Data Loggers are designed for long- and short-term groundwater and surface water monitoring. These non-vented (absolute) water level data loggers measure and record changes in water level, pressure, and temperature. Ensure accurate results by using a Rugged BaroTROLL® Data Logger. All loggers are compatible with user-friendly Win-Situ® Software, which guides you through programming steps, automates level corrections, and accelerates report generation. Simplified Setup and Data Retrieval • Affordable Titanium Data Loggers • • Get reliable data at a budget-friendly price. Use in harsh environments. Solid titanium construction offers chemical- and corrosion-resistance and outlasts speciallycoated data loggers. Select the appropriate logging mode for your project: Linear, Fast Linear, or Event. Flexible Deployment Options • • • Deploy zero-maintenance loggers in flood-prone areas, highhumidity environments, and remote locations. Choose the cable length and termination type that works best for your project. Use suspension wire and backshell hanger for applications requiring minimal instrument access. Save time and reduce errors with the intuitive Win-Situ 5 and Win-Situ Mobile Software platform. Quickly program loggers, download data, graph results, and more. Use a Rugged TROLL Docking Station for programming and downloading data. Connect a cabled logger to a telemetry system, radio, controller, or a SCADA/PLC system via Modbus/RS485 or SDI-12 (only Rugged TROLL 200 and Rugged BaroTROLL). Outstanding Service • • • Receive free, 24/7 technical support and online resources. Order data loggers and accessories from the In-Situ e-store. Get guaranteed 7-day service for maintenance (U.S.A. only).
