I would love to have Nitrates, Phosphorous, Dissolved Oxygen and Ph capabilities also. I suspect that there is a calibration problem for a in stream sensor for these parameters.

Hope your holidays went well. We are looking to purchase materials to engage our technology students with the task of building a Mayfly Logger Station. Could you possibly provide us with a parts/components list of what we need to purchase? We would like to begin with the Spring Semester this year.
Thanks, Jim Coffey Upper Perk HS 267-733-7153
