Probe reconditioning

How often do you need

to recalibrate a pH probe?

Because every use case is different, there is no set schedule for recalibration.

If you are using your probe in a ﬁsh tank, a hydroponic system or any environment that

has generally weak levels of acids and bases you will only need to recalibrate your probe

once per year for the ﬁrst two years. After that every ~six months.

If you are using the pH probe in batch chemical manufacturing, industrial process,

or in a solution that is known to have strong acids and bases, then calibration should be

done monthly or in extreme cases after each batch.

When reconditioning your pH probe is required due to aging, we recommend you use

the Atlas Scientiﬁc pH probe reconditioning kit.
