So I take it the test strips aren’t a good choice for this application?
It seems there are apps for your iPhone that will take a picture of the pH strip, and color identify it, to give you your pH level… That might work.
I also found this accessory for your iPhone, that connects sensors to your iPhone, allowing you to check water. It seems like it might have a good chance of being accessible, but I wouldn’t know that for certain until I tested it…
It seems they have a few different sensors, so I’m not real sure of the differences, but if anyone is interested they are at http://smartaquameter.com/smart-meters.html
One is just a pH tester it looks like for practically $200. (Outch), but another that says it is a 3 in 1 is only $145… not sure what’s up with that.
So, I have some possibilities, just not sure if they are good or bad.
I have a little price shock though, I know that. lol
