OK - I don't want to make a long story longer - but here goes.
I have a Hanna Piccolo - its been fine for about 3 years . I store it in
I have recently cleaned it with a cleaning solution. I also replaced the
It calibrates fine at 7.00ph and at 4.00ph. It measures wine ph fine.
... but when I try to use it to measure TA - i add NaOH solution in drops
and watch the
ph rise until it reaches 7.23 - above which it will not register - no matter
how much NaOH I add.
This is a recent development - and it worked fine on my last batch of wine
So the question is - does this behaviour sound familiar?
- is the electrode pooched?
- are there any homegrown mixtures of high ph - ie. alkaline which I could
calibrate or at least check over 8.0
- Finally Tom S you mentioned you didn't like the probe-to-meter contacts
(agreed) and that you soldered them. - Well my _other_ hobby is diy tube
amps - so I have the tools to solder - but I would love to see a picture of
what you did to your Piccolo - because maybe I just have a contact issue?
