The In-Situ Level TROLL 700 Water Level Logger contains everything needed for water level measurement and logging - level and temperature sensors, data logger, and internal power - all in a 18.3mm (0.72 in) diameter housing with a lot of exciting new capabilities. The instrument is built entirely from rugged titanium with TIG-welded seals, eliminating the potential for flooding from faulty O-ring seals.
The 700 series of the Level TROLL offers new logging modes such as Linear, Linear Average, Event, True Logarithmic, Step Linear, and Fast Linear for complete customization. Additional benefits of the Level TROLL 700 include Pause and Re-Start logging features, a larger memory (350,000+ data points), 0.25 sec sampling (4 samples per second), ability to store and manage up to 50 log files, user notes, advanced compensation settings, and more.
The Level TROLL 700 offers Twist-Lock connectors that provide a secure connection between the sensor and cable. The Twist-Lock connectors are also extendable, allowing the user to easily lengthen the cable without purchasing a complete replacement assembly. In-Situ's new ultra low-power system guarantees 5 years or 2 million readings. For added flexibility, the instrument can also be powered externally. System integration is easy with built-in RS-485 Modbus, SDI-12, and 4-20mA communication output capability.
