Innovations in Water Monitoring Level TROLL® 400, 500 & 700 Data Loggers Be Reliable Get water level data the way you want it, when you want it with industry-leading water level/pressure and temperature data loggers. By partnering with In-Situ® Inc., you receive durable Level TROLL® Data Loggers that provide years of service, accurate results, intuitive software, and real-time functionality. Increase productivity: Reduce training and installation time with In-Situ Inc.’s intuitive software platform and integrated components. Patented twist-lock connectors, included on Level TROLL Loggers and RuggedCable® Systems, ensure error-free deployments. Set up real-time networks: Access data 24/7 and receive event notifications when you connect data loggers to telemetry systems, radios, or other third-party data collection platforms. Control gates, pumps, alarms, and other equipment by using built-in Modbus/RS485, SDI-12, or 4-20 mA communication protocols. Streamline analysis and reporting: Automate water level corrections and post-processing, graph data, and accelerate report generation with Win-Situ® Software. Easily export data to Excel®, a web-based management service, or data analysis software. Deploy in all environments: Install loggers in fresh water, saltwater, and contaminated waters. Solid titanium, sealed construction outperforms and outlasts specially-coated data loggers. Log accurate data: Get optimal accuracy under all operating conditions. Sensors undergo NIST®-traceable factory calibration across the full pressure and temperature range. For applications requiring the highest levels of accuracy, use a vented (gauged) system. Get long-lasting operation: Reduce trips to the field with low-power loggers that typically operate for 10 years. 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). Aquifer characterization: slug tests & pumping tests Coastal: tide/harbor levels & wetland/estuary research Hydrologic events: crest stage gages, storm surge monitoring, & flood control systems Long-term, real-time groundwater & surface water monitoring Mining & remediation
