“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.

The Aqua TROLL 600 simplifies the process by letting us quickly collect up to 1,200 data points per kilometer of nitrate data. We [also] use the logger to ‘sanity check’ the data from other sensors when we put the boat in the water every day.

With the Aqua TROLL 600 and HydroVu, we get better data, better reports, and have a better handle on what’s happening in the river. If it’s sunny and dry and we see a peak in turbidity or pH, we know we should go look. There may be an illicit discharge.

VuLink has changed my life. It’s so simple to use and affordable, and the quality of the data is so much better, it’s really changed the game for us.
