Is it possible to get the ADV6600 in an “EDS” configuration where the dissolved oxygen
membrane is mechanically cleaned by a brush attached to the turbidity sensor?
No. In the released configuration of the ADV6600, the EDS wiper arm would impact the ADV
stem, preventing the wiper from making a complete rotation.
Will the ADV6600 have CE certification?
No. At release, the instrument will not bear the CE sticker. In the future, changes may be made to
the internal circuitry to allow the instrument to meet CE requirements.
I know that the ADV6600 can be purchased with a pressure sensor. Does the system software
convert this data into water depth or level (accounting for barometric pressure, temperature,
and conductivity)?
No. At release, the only output will be in pressure units such as psi or dbar and the system is not
designed for long-term deployments that require a high level of depth or level accuracy. Further, the
pressure sensor cannot be vented to automatically remove the effects of barometric pressure changes
on the overall reading. Although the pressure sensor can measure even slight changes in water level,
the data is not automatically corrected for offsets due to barometric, temperature, or conductivity.
Users may choose to export the pressure data to an Excel spreadsheet and manually compensate for
temperature, conductivity, and atmospheric pressure changes to allow for an accurate reading of the
water level (given that the necessary information is available).
What battery life can I expect from the ADV6600?
The 8 alkaline C cells will provide approximately 30 days of operational time with all water quality
sensors active while taking a 1-minute measurement every 15 minutes (i.e., averaging interval = 1
minute, sampling interval = 15 minutes). Using longer sampling intervals will extend battery life
(but not at a rate that is directly proportional to the difference in sampling interval). . Using the same
one minute averaging interval as above, YSI predicts a battery life of approximately 50 and 80 days
at 30-minute and 60-minute sampling intervals, respectively. Battery life will also be extended
significantly if only one optical probe is utilized.
