PH tester...

Can anyone possibly tell me where I might look locally for an accurate PH level tester?

I know a pool shop will carry them, but I do not know if they are accurate (to the tenth) and down in the 0-1 ph range which is where it is needed.

I don't need anything fancy and digital, just fairly accurate. I couldn't seem to locate one today anywhere.

Thanks.

This is the lowest cost meter that I've seen

there are somewhat similar models by various vendors that run from a bit more to about twice this one.

There are some cheaper soil or water testers, but all the ones that I have seen have a limited range (normal natural pH) and aren't quite that accurate.

I think you'll only find it in a digital format. To read to a tenth of a unit on a full pH scale will require a decent size meter, and those are not cheap.

Not knowing where you live, I can't say if you can find a low end unit locally. Likely you will have to purchase it

You can find similar units listed for less on eBay. Generally the shipping costs are inflated to allow a low minimum bid, it may cost you about the same to buy directly from a vendor.
