pH Probe, BNC-M

The electrode provides approximately a single digit pH value change for every 5 mV change in the electrode reading, either positive or negative depending on whether the pH is above 7 or below it.
~ A neutral buffer solution of pH 7 reads about 0 mV
~ A solution with a pH of 10 reads about 15 mV
~ A solution with a pH of 3 reads about 20 mV
