ORP=>Oxidation Reduction Potential... measured in millivolts(Eh).
Sometimes called Redox levels.
They make specific ion probes(NO3, Ca, Ba, F, etc), you can use these on a number of ion meters. They are not cheap(200-400$ each per probe, then you need calibrate them)
This data can be downloaded etc.
Generally the cost and folks doing the research stick with one machine or parameter at a time or work in teams to measure the parameters.
It's a lot of work.
