“We first tried the Level TROLL® 500 at The Rigolets, the saltwater outlet of Lake Pontchartrain to the Gulf of Mexico. The sensor’s titanium body stood up against zebra mussels, barnacles, and the corrosive effects of saltwater, making it more reliable than any other instrument we’ve used in this challenging environment.”
