2. After installing the new electrode to your meter, a 3-point calibration must be performed to ensure
the accuracy.
How to Use the Electrode
1. There is a proper amount of storage solution in the storage bottle on top of the electrode. The pH
glass sensor tip is soaked in it to keep its sensitivity.
2. Before measuring, loosen the bottle cap, then pull out the electrode while twisting
counterclockwise. Place the storage bottle at a safe position.
3. Rinse the electrode with purified water and shake off excess water or blot-dry it with clean tissue
or filter paper. Never rub the glass membrane.
4. Insert the electrode into your sample solution and stir it for a few seconds in the solution to remove
potential air bubbles, which may cause unstable readings. Then wait for the stable reading and take
the measurement.
5. After use, insert the electrode while twisting clockwise into the storage bottle, then tighten the
bottle cap. If the KCL storage solution (SKU: AI1107) in the cap is contaminated, please fill in
new storage solution (other brands’ storage solution may not work with this electrode).
How to Maintain the Electrode
1. Always rinse the electrode with purified water (distilled or deionized water) before and after each
test and calibration. For general contaminants stuck on the glass bulb sensor, use warm soap water
and a soft brush to clean off; For special contaminants, please refer to the following table for proper
cleaning solutions:
