Hi folks,
I bought a second hand Bluelab PH meter (the guy claims it hasn't been used, but let's assume he could be lying).
Saved me bout 25% of the cost of a new one which admittedly isn't much (but it's good if the meter is in perfect nick).
I know that for long term, the meters should be stored in liquid and not be allowed to dry out.
When it arrives, how would I know whether it has been stored incorrectly or dried out or whatever?
If I pH test it / callibrate it, and it's fine, then does that mean all is ok and I can forget about it?
Thanks
