Replace your old pH electrode in your Hanna pH Pen for accurate and reliable readings.
Hanna's spare pH electrode is made to be replaced easily and lock into place. Replacing the electrode only takes a few seconds and does not have any delicate pins that could break. Use the replacement electrode tool that is included with the pH pen to expertly replace the electrode in your HI98129 pH Combo Pen.
We recommend calibrating your electrode any time that a new one is installed.
