Uhm, i think there’s have quite a bit of a misunderstanding… pH/EC probes are ALWAYS submerged, because otherwise they can’t measure anything, and the electrical isolation has nothing to do ...

(For example, a pH of 10.1 reads 0.101V.) To tweak the circuit, place the pH probe in other standards and adjust the Y-intercept potentiometer. Note again, if the temperature changes, you must ...

Some pH meters have in built temperature measurement probes, while in other cases an external temperature probe may be required. Using external or internal measurements, the temperature values ...

In conditions where temperature is variable, it is advised to add a temperature sensor in the pH meter. The sensor measures the pH based on the temperature corrected slope.
