Along with the large oceanographic buoys, Resinex can manufacture smaller instrumental buoys usually used for monitoring purposes in lakes, port areas and shallow waters in general.
In search of innovative monitoring tools, in 2019 Corr-Tek required 4 instrumental buoys with a net buoyancy of 76,5 kg in order to implement the live water quality monitoring, with the aim to maintain the natural ecosystem and facilitate the sustainable growth of the Mincio River Regional Park (Mantua, Northern Italy).
In the same year, Colmar installed 3 Resinex buoys for environmental monitoring in the port area of La Spezia (Liguria, Northern Italy). The buoys were equipped with a multi-parametric CTD probe and a data acquisition and transmission system. Oxygen concentration, turbidity and pH of water were the main monitored parameters.
Other companies that Resinex has recently supplied with small instrumental buoys are the Italian Apphia and Biosurvey, an academic spin-off of the University of Palermo specialized in advanced technologies applied to aquatic systems.
An environmental monitoring station in Lake Garda
The University of Brescia has recently requested spherical and cylindrical buoys for the creation of a fixed floating station to be placed in Lake Garda, close to the Natural Park of Manerba. The aim is the real-time measurement of air temperature and humidity, wind speed and direction, solar radiation and temperature of the water column. The station is composed by a section emerging from the surface for about 2 m, where meteorological sensors are housed. The support column, that dives in for about 6 m of depth, is connected to the floating system composed of 4 floats. Moreover, 2 surface and 2 subsurface buoys allow compensation when the water level changes. The submerged part of the station is composed of a chain of 12 thermistors and an oxygen indicator. A data logger connected with a modem and an antenna for the data transfer via GPRS are placed just below the water surface.
