Every time you run out, be sure to clean the electrode 2. pH calibration If the solution is not recognized, the electrode is broken.

Dear customer friend,thanks for your support,pls note that ph meter need 3x1.5LR44 batteries, because if the product with battery, the customs will not pass, so the product not include the battery, and product come without retail box, hope you can understand, thank you.
