How old is old when it comes to probes? I have an old brs blue cap ph probe its prob 5yrs +/- old.
Would it even be worth re calibrating and using or should i just get a new american pin point probe? Thanks

It will be used to monitor my ph inside my cal rx.

I have never had a ph probe last 5 years, but maybe that just my bad luck lol. Cheap/expensive/inbetween i seem to get a few years max out of one.

I would replace it, considering it’s actually controlling something. Now if it was just monitoring something I would suggest recalibration it till it’s reaction time was rediculously slow.
