We have released a promotional video for the pH electrode cleaning agent "Seez Mild"!

We clean the electrode and maintain the pH value! Introducing the pH electrode cleaning agent "Seez Mild."

Is the sensitivity of the electrodes in your neutralization device okay? There may be a possibility that it is not neutralizing properly and is flowing due to "taking time for measurement" or "fluctuations in pH value." 'Seez Mild' cleans the electrodes and maintains the pH value. [How to Use] ■ After pouring about 200ml into a beaker or similar container, immerse the pH electrode for 2-3 minutes, then thoroughly rinse the electrode with tap water. * If the electrode is heavily soiled, please wipe off the dirt well with a soft paper or cloth. * For more details, please refer to the PDF document or feel free to contact us.
