You are far better off with one of these

I do water testing for the state and I have used a range of digital
testers, my current one is an $8000 YSI Pro and if I don't calibrate
it every time I use it, the results are all over the place. A cheap
one you do not calibrate is just a random number generator that may
give you a rough idea of pH but I would not trust it. The chemical
testers may not get you out to 2 decimal places but it will be
accurate +/- 0.4 points every time.

Good comments by someone who appears current. I'm a retired chemist but
it has been years since I worked at the bench. pH meters were expensive
and finicky and now it appears you can get them cheaply but these are
finicky.

I've got a bunch of old pH papers left over from my lab days. Work OK
but maybe no more accurate than half a unit which is fine for most of
the stuff I want to check like house water and soil.

What was the problem? I worked for Orion Research back in the early '80s
and recall the Ross electrodes as being quite stable. I'm a programmer
though and not a chemist so I viewed them as a voltage source for the
A/D that gave me numbers to play with.

The chemists were a strange lot, including Dr. Ross.

I just know I have been issued Hanna and YSI water testing instruments
and if they are not calibrated frequently, you can't trust them.
