Figure 4-11 The YSI 600 Multiple Sensor Sonde
The YSI 600 is ideal for profiling and monitoring water condi-
tions in industrial and wastewater effluents, lakes, rivers, wet-
lands, estuaries, coastal waters, and monitoring wells. It can be
left unattended for weeks at a time with measurement param-
eters sampled at your selected interval and data transmitted to
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. Data can be
exported through Flowlink software for further processing.
The YSI 600 connects to a modified 9-pin Rain Gauge Terminal
on any 4200 Series Flow Meter. Operation of the Rain Gauge
with YSI 600 is still possible with a special Y-connect cable. Mod-
ification of older 4200 Series Flow Meters is possible with
changes in connectors and boards. For additional information,
contact Teledyne Isco.
The YSI 600 is available with a cable 25 feet long 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.
