Wieteke I use the Vernier probes and data logger for my natural history class. They work quite easily; a few require calibration before you go out for the day. I am pretty sure they have probes for what you want to measure, and the system is not prohibitively expensive. To save on equipment costs, I just use a refractometer for measuring salinity.

Hello Ecologgers! I work on Midway Atoll NWR as a wildlife biology volunteer and I'm helping to set-up monitoring efforts to determine environmental/weather factors affecting the occurrence of botulism outbreaks among ponds/freshwater seeps around the atoll. We would like to monitor for a variety of factors and I was wondering if any of you have recommendations for devices (preferably devices that can do multiple functions and are not cost-prohibitive) to measure the following: -water temperature -water salinity -water pH -conductivity -water salinity -redox potential -turbidity -dissolved oxygen Thank you! ~Wieteke Holthuijzen
