Origins of the Sonde and ISCO

• Donated to the TCSWD by the Tippecanoe Health
  Department.
  
• The equipment has been in storage until this fall
  when we began working with it.
  
• The TCSWD wants us to evaluate the equipments
  current conditions and give them easy to follow
  directions.

ISCO Specifications

• Portable sampler
• Programmable to take samples at predisposed time
  increments
  
• Samples are stored in an insulated base
• Data is stored in its large memory (2mB) and can
  be retrieved with the 581 Rapid Transfer Device

7
Sonde Specifications

• YSI Environmental
• Field replaceable probes
• No internal memory or battery
• Must be hooked up to sampler, data logger, or
  computer
  
• Operational temperature
• -5 to 45oC

ISCO hookup (Sonde)
10
ISCO hookup (RTD)
11
Computer hookup (Sonde)

• Direct hookup of Sonde to computer
• Incompatible flowlink 4 software.
• Manual calls for Ecowatch software

12
EcoWatch Software

• Collects data from the Sonde when directly
  connected to the computer
  
• Collects and graphs real time data

13
Probes

• D.O., pH, Turbidity, Conductivity,and
  Temperature
  
• Each probe has been detached and cleaned
• Temperature, D.O., and pH probes have been
  calibrated.
  
• May need to replace the pH probe

Conclusion

• To Date
• Cleaned and calibrated most of the probes
• Successfully connected Sonde directly to
  computer
  
• First attempt at programming ISCO sampler
• Began writing program manual
• Website http//epics.ecn.purdue.edu/cwwq/
• Future (tentative)
• Program ISCO sampler and test battery life
• Test data transfer from ISCO sampler to computer
• Price replacement pH probe
• Complete calibrations
