PH Tester should be calibrated prior to use with our pH buffer solutions. To calibrate:

1. Clean electrode with distilled water
2. Dip electrode into 4.0 pH buffer solution. If the meter does not read between 3.9-4.1, adjust meter using adjustment screw on back.
3. Clean electrode with distilled water
4. Dip electrode into 7.0 pH buffer solution. If the meter does not read 7.0, adjust using adjustment screw inside battery cover.

pH 10 buffer solution should be used to calibrate when testing high alkalinity solutions.
