I calibrate my PH probe every 6 to 8 months.

Average, once a year. I have secondary measurements and they usually are in line with the probes.

hi TRIGER and Boa! if you want to have an accurate reading of PH and ORP we suggest to calibrate probes every 3 months.
If you make the calibration every 6-8 months ok, no problem but the reading you have will not be so accurate.
