In-Situ® Water Level Data Loggers

Economical Water Level Data Loggers Offer Absolute Convenience

Non-vented water level data loggers collect water level, pressure, and temperature data in remote, flood-prone, or high-humidity environments.

• Rugged TROLL 100: Use for long-term logging in locations with minimal access.
• Rugged TROLL 200: Use for routine logging and real-time access.
• Rugged BaroTROLL®: Use in conjunction with Rugged TROLL Loggers when you need to compensate for barometric pressure fluctuations.

High-Accuracy Water Level Data Loggers Excel in All Conditions

In-Situ manufactures narrow-diameter loggers with a range of pressure options and logging modes. Record water level/pressure and temperature measurements and connect to a your data collection platform.

• NEW Level TROLL 400: For absolute convenience, choose this non-vented data logger for use in flood-prone, high-humidity, or remote locations where a desiccant system isn't practical. Deploy with a BaroTROLL Data Logger for highest level of accuracy.
• Level TROLL 500: Use this vented logger when you need automatic pressure compensation and typical logging options—Linear, Fast Linear, and Event.
• Level TROLL 700: Use this data logger for applications with unique logging requirements. The Level TROLL 700 features Linear, Fast Linear, Linear Average, Event, Step Linear, and True Logarithmic logging modes. Vented and non-vented units are available.
• Level TROLL 700H: Meet the Office of Surface Water specification of ±0.01 foot with the industry’s most accurate water level logger.
• Aqua TROLL 200: Use this CTD logger to measure water level/pressure, conductivity, and temperature. This sensor delivers the highest levels of accuracy in saline or brackish water environments.
• BaroTROLL: Use alongside non-vented loggers that require barometric pressure compensation. Or use with gauged systems to calculate barometric efficiency.
