I just bought an electronic pen type PH tester. Seems like a good idea,no?
I tested it out on plain water which read 7.0, and it says to also use borax mix which should read around 9.41. My pool water read 7.35, the strip read 7.4 and the drops read 7.2, close enough for home work.
We use all electronic meters for all of our Boiler water and demin water readings, we do very few manual readings, My eyes can't seem to look at another colored strip or drop comparison chart.
Anyone use any of these items? Anyone know about a CL meter like this?
