ph calibration - which numbers to use?

Post by rossbryant1956 »

I was recalibrating tonite and came up these numbers:

When doing the 7.0 I got

ph 7.0 510
539
ph 10 592

When I changed to the 10. 0 I got

ph 7.0 500
827
828

Thx to all. looking for the values for phMin and phMax

If I change my phmin from 539 to 510 which way will my ph number go? Up or down. My Ph testing is always higher than my probe. Thx
