Multiparameter Testing
The Solinst Levelogger 5 combines a pressure sensor, temperature detector, 10-year lithium battery, and datalogger, sealed within a 22mm x 160mm (7/8" x 6.3") stainless steel housing with a corrosion-resistant coating baked-on using polymerization technology.

Hastelloy Pressure Sensor
The Levelogger 5 measures absolute pressure using a Hastelloy pressure sensor and offers high resolution and an accuracy of 0.05% FS. Readings are stable in extreme pressure and temperature conditions. The Hastelloy sensor can withstand 2 times over-pressure without permanent damage. Combined with the durable coating inside and out, the Levelogger 5 has high corrosion and abrasion resistance in harsh environments.

Protective Design
The logger uses a Faraday cage design, which protects against power surges or electrical spikes caused by lightning. Its durable maintenance-free design, high accuracy and stability, make the Levelogger 5 the most reliable instrument for long-term, continuous water level recording.

Questions & Answers
What is the warranty period for the Levelogger?
Most standard products from Solinst carry a 3-year warranty, stating that items should be free of workmanship and material defects. There are some additional conditions that are outlined in Solinst' warranty statement found here: https://solinst.com/about/warranty.php 
Can the Levelogger be used in saltwater environments?
Yes. Leveloggers have a corrosion-resistant coating. In harsher environments Solinst recommends taking additional steps to protect the logger. More information can be found in the user guide, page 76. 
Can the Levelogger be connected to an external data logger?
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.
What is the difference between the Solinst 5m range Levelogger 5 loggers and the 10m, 20m, 30m, 100m and 200m loggers?
The main difference between the loggers varying depth ratings is the tolerance in different pressure ranges, followed by the accuracy and resolution. The specifications sheet shows the resolution of each logger in the table on the last page.

Monitoring Lake Erie’s Eastern Basin: Building Long-Term Data and Real-Time Public Solutions

In the eastern basin of Lake Erie, off the coast of Dunkirk, New York, a data buoy collects valuable water quality, weather, and wave data that inform residents and regulatory groups of conditions on the water. Since 2011, Buffalo State University’s Great Lakes Center has maintained and operated the Dunkirk buoy with funding from the Great Lakes Observing System (GLOS) and field support from the NYSDEC Lake Erie Fisheries Research Unit. [caption id="attachment_38976" align="aligncenter" width="940"] The Dunkirk Buoy viewed from the research vessel after being deployed in early spring.
