![]() I would calibrate it with 4.0 and 7.0 this will make more accurate at a predominate level of 6.60.

![]() might make it more accurate but the slope is probably close enough for a reactor with 7 and 10.
Should try a little experiment with a solution of say around 6.6 or at the least cal with the 7 and 10 and tell us what the 4 comes in at. |

![]() Typically when using a PH probe to measure your tank PH you Calibrate at 7 and 10. If you are using the probe in a CA reactor you Calibrate and 4 and 7.
The difference is very noticable when using the probe in the reactor. I went from calibrating at 7 and 10 to 4 and 7 and my probe rose 0.4. That is a lot when it come to melting Calcium carbonate J |
