    11 in stock In stock

    The Aqua Master Tools replaceable EC, CF, PPM, Temp electrode is easy to connect using the PIN connector. With most conductivity meters, the electrode cannot be replaced because they generally do not break if properly maintained. However, due to aging, limescale, leakage in the electrode or cable breakage due to hardened plastic, the electrode can break. That is why the electrode on our meter is replaceable. We recommend storing the pH electrode with KCl storage solution in the protective case.

    The Aqua Master Tools replaceable pH electrode is easy to connect using the BNC connector. Due to the long double junction pH electrode, it has a longer service life. Over time, pH electrodes age, with proper care and regular cleaning, the lifespan is extended. However, over time, the reference liquid in the electrode will become contaminated and the electrode will respond more slowly or stop working altogether. The electrode will then need to be replaced. We recommend storing the pH electrode with KCl storage solution in the protective case.
