4.11 YSI 600 Multiple
Parameter Sonde
The YSI 600 Sonde is a multi-purpose, water quality mea-
surement and data collection system. It is intended for use in
research, assessment, and regulatory compliance. The YSI 600
Sonde can measure the following water qualities:
• Dissolved Oxygen
• Conductivity
•pH
• Salinity
• Total Dissolved Solids
•Temperature
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 pro-
filing. 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
processing.
The YSI 600 is available with a cable 25 feet long that connects
to the flow meter. The cables are waterproof at the sonde and can
be used in lab or field.
