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.
