For probe cleaning - Soak it in cleaning solution for about 3 minutes once a day or at least once a week to prevent clogging and to maintain accuracy.

For probe storage - Place a sponge or tissue in the bottom of the cap, and pour some storage solution into the cap.

Never let probe dry after conditioning and Never use distilled/deionized water for storage purposes.

Always rinse the pH electrode with water between calibrations and testings.

Check out the "pH Electrode Care" for more details.

Use pH 7 for 1-point calibration; buy pH 4 & 7 for low pH range 2-point calibration; buy pH 7 & 10 for high pH range 2-point calibration.
