SECTION 2 6920DW AND 600DW-B SONDES
2.1 GETTING STARTED
The 6920DW and 600DW-B-B Drinking Water Monitoring Systems are multi-parameter, water quality
measurement, and data collection systems. Their primary application is the monitoring of drinking water
using a flow cell and a free chlorine sensor is provided with each instrument since this parameter is very
important in assessing the quality of drinking water. However, these instruments can also be used in a
variety of research, assessment, and regulatory compliance applications without a flow cell as long as the
user realizes that the performance of the free chlorine sensor will be significantly compromised under these
conditions. The primary difference between the “DW” instruments and those provided by YSI for surface
and ground water applications is that the oxygen sensor for the standard sondes has been replaced by a free
chlorine sensor in the 6920DW and 600DW-B. The free chlorine sensor also requires a different circuit
board which is resident in the instrument and this means that “DW” sondes are not capable of dissolved
oxygen measurement and, vice versa, standard sondes are not capable of free chlorine measurement even
though the probes themselves will fit in either of the instruments. Section 2 concentrates on how to set up
operate the “DW” sondes. For the purpose of terminology in this manual it should be realized that a sonde
is a torpedo-shaped water quality monitoring device that is placed in the water to gather water quality data.
Sondes may have multiple probes. Each probe may have one or more sensors that read water quality data.
The following list contains parameters that your sonde may measure. See Appendix E Specifications for
the specific parameters of each sonde.
• Free Chlorine
• Conductivity
• Specific Conductance
• Salinity
• Total Dissolved Solids
• Resistivity
• Temperature
• pH
• ORP
• Turbidity
• Nitrate-N
• Ammonia-N
• Ammonium-N
• Chloride
• Chlorophyll
• Rhodamine WT
This section is designed to quickly familiarize you with the hardware and software components of the
“DW” sondes and their accessories. You will then proceed to probe installations, cable connections,
software installation and finally basic communication with your Sonde. Diagrams, menu flow charts and
basic written instructions will guide you through basic hardware and software setup.
