Purchase
Calibration steps:
1) Remove the clear cap (small container) from the pH probe.
2) Immerse the pH probe in RO water to a minimum 4cm (1.5”) depth (maximum 9cm
(3.5”)) for a few minutes (about 3-5 minutes). Gently move and rotate the pH probe
several times in the water.
3) Never expose pH probe to the air for more than 3-4 minutes. The pH probe should
be always in the water or in its transport protection container.
4) After removing pH probe from RO water, gently shake the excess water and wipe
using a fresh paper towel. Never wipe the end probe tip. Just dry by gently touching/
dabbing the end tip with paper towel.
