the flow meter. You can use the YSI 600 as deep as 200 feet below
the surface, or in as little as a few inches of water. The fast sensor
response of the YSI 600 makes it ideal for vertical profiling. Its
small size means it can fit inside two-inch diameter monitoring
wells.
A Rapid Pulse Dissolved Oxygen Sensor eliminates the need
for stirring, providing accurate results without an expensive and
bulky stirrer. Because no stirring is required, no supplemental
power supply or battery is needed, and sensor drift caused by
passive fouling is minimized.
The YSI 600 communicates with any 4200 Series flow meter
equipped with suitable hardware and software. Earlier model
4200 flow meters can be factory-modified to work with the YSI
Sonde. Data can be exported through Flowlink for further pro-
cessing.
The YSI 600 is available with a 25 foot cable to connect to the
flow meter. The cables are waterproof at the sonde and can be
used in lab or field.
Information about programming the flow meter to use the YSI
600 is found in Section 2 of this manual. Information about the
YSI 600 Sonde is found in the YSI manual.
