pH Probe Replacement

[AllSignsPointToFish]

I've had my single-junction pH probe for my Apex classic in service for four years. I calibrate it several times a year. How often should the probe be replaced? I know pH probes don't last forever.

Is a double-junction probe compatible with the Apex classic?

They sure are! I run the BRS double junction Ph probes! And I calibrate then once or twice a year

Sweet. Thanks for the input!

Depends on whom you ask. I’ve seen ranges from 6 months to 2 years. I typically replace mine every 2 years unless it fails to keep calibration earlier.

Guess it might be time to consider replacing mine

Probably depends on quality of probe but 1-2 years is what most recommend
