Description
The LeveLine-Gauge is a water level and temperature logger designed for long-term deployment in diverse aquatic environments, including harsh and saline conditions, thanks to its durable all-Titanium body and comes with a 5-year warranty. The LeveLine-Gauge comes as a sealed unit with an integrated data logger, capable of storing 500,000 data points, vented Pressure Sensor and vent tube to the surface. The whole unit is housed within a 22mm x 186mm all-Titanium body, ensuring resilience in demanding environments, and can be powered by a 10-year Lithium battery or an external 6-24vDC supply. SDI-12 and RS485/Modbus communications interface for external logging and the device is supported by LeveLink PC software for data processing and can be easily deployed using the Leveline QuickDeploy Key to commence logging onsite.
