I need to borrow this if anyone has one I can use. Need to see what my TDS is on the input to my RO unit and the out put.
I finally found one. got it from Blue Planet, it was used but hey I got one and I am happy no more trips to kroger.
Also, if someone does happen to have a PAR meter I can borrow as well. I'm curious to see what my lights are putting out.
