Overview
The Solinst Levellogger 5 LTC combines a datalogger, 8-year battery, Hastelloy pressure sensor, temperature detector, and conductivity sensor within a small waterproof housing, 22mm x 208mm (7/8" x 8.2"). A baked-on coating using polymerization technology protects the body against corrosion, abrasion and high temperatures. The conductivity sensor is a 4-electrode platinum sensor with autoranging capabilities. The minimal-maintenance, sealed Levelogger 5 LTC is simple to clean and calibrate, even in the field.

Yes, the Levelogger can be integrated with an external data logger via SDI-12 output through the use of a direct read cable and SDI-12 interface cable (PN# 115133). Please see the Accessories tab for pricing on these options.
No, a USB Interface Cable attaches to the topside connector of Leveloggers deployed with L5 Direct Read Cables, allowing for communication with a PC in the field.
Yes, a Solinst Levelogger App Interface (part 115009), allows Bluetooth connection of Leveloggers to Android and Apple devices.
No, the Solinst Levelogger LTC is an absolute logger, meaning that it is sealed from the atmosphere and records both barometric and water pressure data. Because of this, the data will need to be paired with local barometric pressure data to compensate for effects on the water level within the well.
Solinst offers a vented logger, the LevelVent which can be found here: https://www.fondriest.com/solinst-levelvent-5-water-level-loggers.htm

Environmental Dredging and Remedial Construction
Though dredging is often painted in a negative light, dredging initiatives and projects are often conducted to improve environments, begin recovery periods for water beds contaminated with toxins, and reinvigorate ecological systems and habitats. Many of the technicians and engineers who plan and execute dredging projects are dedicated to balancing the economic benefits of dredging with protecting the environment. Sevenson Environmental Services Inc. provides sediment remediation as one of many key services offered to help restore natural environments. Steven Shaw spent more than a decade working as an engineer on various dredging projects before finding his way to Sevenson eight years ago.

Caring for the Chesapeake: Supporting the Iconic Bay Starts with Good Monitoring Data
The Chesapeake Bay is enormous: the Bay and its tidal tributaries have 11,684 miles of shoreline—more than the entire U.S. west coast. It is the largest of more than 100 estuaries in the United States and the third largest in the world. The Bay itself is about 200 miles long, stretching from Havre de Grace, Maryland, to Virginia Beach, Virginia. But the Chesapeake Bay isn’t just enormous--it’s enormously important. The Chesapeake Bay Program reports that its watershed covers about 64,000 square miles and is home to more than 18 million people, 10 million of which live along or near the Bay’s shores.

Treating Harmful Algal Blooms: A Natural Progression
Some of us happen upon the subject of our life’s work by accident, some of us are born into it, and some of us ease into it over time. For Tom Johengen, Research Scientist for Cooperative Institute for Great Lakes Research (CIGLR) and Director of Michigan Sea Grant , choosing to study Harmful Algal Blooms (HAB) was “a natural progression” from his days as a grad student investigating best management practices for controlling nonpoint source nutrient pollution. “I’ve been the research scientist with CIGLR since my postdoc in 1991, 31 years, and I’ve been the Director of Michigan Sea Grant for the past 3 years. When I began my postdoc with CIGLR we were just starting to study the impacts of the recently invaded zebra mussels.
