Anyone ever looked at these meters?
They don't seem to have brand names on them.

www.mcmastercarr.com
search for "PH meter"

I am looking to get a new meter.

You should have posted the link to the actual page or mentioned the
model your are cosidering, there are 3 pages of meters there. That
said the first one looks like a Hanna pHEP, but the accuracy spec is
odd; pH is a log function and it's speced in a linear value. I did
not want to go to the effort of converting it since the cost makes me
wonder how good it can be.

You want an accuracy of at least 0.1 pH units, preferably better,
resolution of pH 0.1, preferably better.

You can get good meters at Fisher Scientific, Cole Parmer, Sargent
Welch and most winemaking stores also. Since the McMaster Carr
catalog has drawings I really can't tell what the are, but it looked
like a few might be good enough.

If this is a hobby meter you should be able to find one you want for
under $100 US, if it's for a professional setup a good bench meter is
usually under $300 and you can pick your probes and replace them as
needed.

Don't forget you need calibration solutions, the cheapest way to go
there is to find a source for Hydrion capsules, they are added to
100ml of distilled water to make the buffer solutions so you get what
you need when you need it.

The cheapest meter I know that fits the bill is the pHEP 3 at around
$50 US, the pHEP5 is much better for around $70 from Grainger or
Hanna. There are lots of othe manufacturers out there and it really
depends on what you want to spend. The more you spend the more you
get usually.

Hope that helps.
Regards,
Joe
