59 x 3 178. No more electrode breakage or clogged junc. The DW rinse between these keeps either calibration solution from changing pH of the other slightly due to the residual on the meter from the last solution it was stored in.

Rinse the electrode on the pH meter with distilled water and wipe dry with a paper towel. If the display shows a pH of 7 accept the reading. For example a pH probe in pH 7 has a mv of -15 and in pH 4 193 mv the slope would be 193-15 178 mV Theoretical is 5916 mVpH 25 oC.

A tester will give you decent accuracy as long as it is taken care of. First check the pH electrode for contamination or damage. The probe has 100 slope.

You could use lemonlime juice in a cup of water you should test water with tester to see if its ph is at 7then slowly squeeze either limelemon juice in the water and stir.
