Replaceable pH electrode for AD-11 & AD-12, ADWA

Replace your testers' electrode if it cannot be calibrated and/or readings are unstable.

With the ADWA replacement probe, your AD11/12 pH meter is quickly ready for use again: Simply unscrew the ring at the top of the electrode and then replace the existing probe with the new one.

Important: Before using it for the first time, the replacement probe must also be adjusted using the calibration solutions of your pH meter.
