Be sure to buy it from a place that has fairly rapid turnover, as they
don't have a great shelf life.

And my advice would be, unless you experience has been markedly
different, to not bother with this new probe and invest in a better
meter that has a better probe. My first Checker1 probe did not work
well at all (had been on the shelf far too long before I purchased it)
and the replacement I bought worked great -- but only for about a year
and a half before it went completely haywire, in spite of being stored
properly in the recommended buffer solution. All the advice I've
gotten is that the probe is the most important part of a meter and the
Checker1 probes that you can get for as low as 12 or 13 bucks (US)
just won't cut the mustard for long.

I'm still a little wary of Hanna products given that they sell a
product that from my experience is so unreliable, but people seem to
have had generally excellent experience with the pHep5 and so I'll
probably be buying one of those real soon.
