In-Situ Level TROLL 500 Vented Level LoggerThe In-Situ Level TROLL 500 simultaneously measures and logs water temperature and level and is designed for ground- and surface-water monitoring in both fresh and saltwater environments.

The self-contained instrument includes the sensors, data logger, and internal power, all in a 0.72-inch-diameter housing. With an exterior constructed of titanium and TIG-welded seals, this rugged level logger is capable of long-term deployment without experiencing corrosion or flooding. It offers Twist-Lock connectors that provide a secure connection between the sensor and cable. The Twist-Lock connectors are extendable, allowing the user to lengthen the cable without needing to purchase a complete replacement assembly.

The sensor’s vented cable allows atmospheric pressure to be applied to the back of the pressure sensor, canceling out the effect of external atmospheric pressure fluctuations. The gauged barometric sensor on the TROLL 500 measures true water level elevations within +/- 0.1 full scale.

The TROLL 500’s internal power supply ensures a minimum of five years of battery life, or two million readings. The device can also be powered externally with a battery pack or other supply.

The TROLL 500 has many other convenient features. Deleted files can be “undeleted,” avoiding the accidental loss of data. Data is also automatically collected and saved according to the site it was taken at. The unit can also be easily integrated into monitoring systems, as it has RS-485/232, Modbus, SDI-12, and 4-20mA communication output capabilities.
