How long do apex pH probes last

Jyetman · 03/27/2017, 03:13 PM

I purchased my full classic Apex in March 2014 so today my lab grade pH probe is 3 years old. Just finished calibrating it after a vinegar cleaning. It gave me no problems calibrating and is still reading properly. How long do these probes last?

I've had the regular probe go 3 years before drifting; imagine the lab probe would do somewhat better.

I purchased a pH pinpoint BNC replacement probe during black friday thinking I'd be soon replacing the Apex probe. How long can this new pinpoint last sitting on a shelf waiting?

Just replaced one of my Neptune Lab Grade pH probe after 3.5 yrs. Not bad IMO.

My lab grade probe from 2014 is still in service. Time for my annual calibration soon.
