The OTT measuring buoy was designed particularly to work in combination with the Hydrolab Multiparameter Probes for water quality monitoring applications. Like the OTT CompactStation this buoy is equipped with a data logger unit connected to a GSM data transmission unit and has an autarkic power supply. Differently than with conventional buoys, the mulitparameter probe is installed laterally in a pipe, so that the buoy does not have to be opened for maintenance and calibration, which have to be carried out regularly for accurate measurement of water quality. The measuring buoy can be reached from a small boat and the necessary maintenance works can be done easily. |
