Many pH electrodes are shipped with the electrodes moist. Prior to using your electrode for the first time it needs to be conditioned. While it is always best to refer to the manufacturer instructions for proper electrode conditioning, below are three common recommended steps for conditioning your electrode:
- Remove the protective cap or bottle from the bottom of the sensor and rinse the electrode with distilled or deionized water and blot with a Kimwipe®.
- Place the electrode in a beaker containing one of the liquids listed below (in order of ionic ability to condition the electrode.) Soak for 20 minutes.
3.0 M KCI
4.0 pH buffer
7.0 pH buffer
Note: Never condition or store a pH electrode in water long term exposure to purified water will damage the special glass membrane. - After conditioning the sensor for 20 minutes, rinse the electrode with distilled or deionized water and blot with a Kimwipe. The electrode is now ready for calibration and to measure pH.
