|Lonesomedave ||09-19-2013 09:00 AM |
anybody have any experience with those inexpensive ph meters that they sell for swimming pools, etc
i refer specifically to the ones the go from 0-14....
are they accurate and how much trouble are they to maintain, calibrate etc

I think I had to check the pools ph using a water sample. You'd drop a few drops of this solution into the sample and see which color it turned. There was a little color chart to check it against.
Something like this:

If you are talking about the PH meters that work by dipping in your water, the ones popular with hydroponic growers, I went to a family reunion in MI this past summer and my cuz is a (legal) weed grower there. He gave me a mini tour of his hydroponic grow and among his tools he had several of them so apparently they are good enough for hydroponic weed cultivation.

Depending on what you want to use, keep in mind that many of the cheaper electronic ones don't work too accurately at the extremes (pH ~1-3 & pH ~11-14).

Bloodhammer would probably be the expert on this. I think he maintains pools as a profession.

Not often, thank the gods. I mainly repair and replace equipment and run wires and pipe. I'm not all that good with the chemistry side of it, but if you want to know how to fix a gas pool heater, I'm your man. Just don't get irate if I tell you it needs to be replaced. :rolleyes:
Anyway, I've never seen pH tests for pools that go from 0-14. Typical pool pH tests go from 6-8 because anything above or below that range is considered extreme for pools.
