Sondes may have multiple probes. This is a close-up photo of the end of the 6600 sonde with all sensors installed. Each probe may have one or more sensors that read water quality data. The 6600's used on the DeepWorker are configured with a stainless steel pressure case in the event dives greater than 700 feet are required. The data is then passed to one of the ships onboard computers.
Specialized software is used to graph and manage the data.
The 6600 sonde is designed for long-term in situ monitoring and profiling. The sonde will log all of the parameters at programmable intervals and store 150,000 readings. At 15-minute intervals, it will log data unattended for about 75 days. Visit YSI's web site .
