Installation Section 2
Note: The 6500 Monitor is provided with a weatherproof enclosure that will withstand most
environmental conditions with no compromise to system performance. An optional Weather
Shield (YSI #6505) is available for added protection from the elements.

Locating the monitor near the sonde will have advantages since in-situ (on-line) calibration can
be more easily facilitated under this arrangement. For example, a recently calibrated, hand-held
dissolved oxygen meter and probe can be placed next to the sonde and readings compared
between the monitor and the hand-held meter. In addition, operator checks to verify accuracy and
determine the frequency of calibration for water quality measurement in the flow stream can be
easily carried out with a variety of hand-held manual readings at the time of inspection by the
operator if the monitor is conveniently located.
Two sondes, #6920 and #600XLM, have logging capability. These two sondes are able to store
recorded data into their memory, which then can be downloaded into a PC or Display/Logger. If
the 6500 cannot be connected to a system such as a SCADA, data can still be recorded using one
of these two sondes. The 6500 itself does not record data; it only displays real-time monitoring.
