OTT Water Quality Buoy

Buoy used to measure water quality parameters

The OTT measuring buoy is specially designed for operation in combination with the HYDROLAB HL7 or HL4 multiparameter sondes. It is equipped with a data acquisition and remote data transmission unit as well as a mains-independent solar power supply. Compared to conventional buoys, the multiparameter probe is mounted laterally in a pipe on the OTT measuring buoy. This eliminates the need to open the buoy during maintenance and calibration work, allowing tasks to be easily done from a small boat.To help reduce bio-fouling for longer maintenance intervals the HYDROLAB HL7 sonde is equipped with a central cleaning brush and a copper measuring cap.
