As the question stated, does a broken agcl eletrode will leads to a big measurement error? Means that, you will still get a result but that reading will be highly inaccurate?
Dear Dr. Wan Mohamad Ikhmal,
the breakage or malfunction of any reference electrode could lead to incorrect readings of the potential for free corrosion (Efc) or high instability of this value. Personally, both in the case of potentiodynamic polarization and EIS measurements, I would not consider the data obtained and repeat the measurement in the correct conditions. Already working in optimal instrumentation conditions, sometimes difficult data to explain are obtained .... I would not complicate my life even more !!!

Hello, every serious lab should have a variety of electrodes that are constantly checked for correct potential, leakage rates, impedance and so on.... and each researcher is responsible for his own electrodes.... so, I don't understand your question ;-)
I think it is better to inspect electrode and compare it with standard if there is damage occurred before used and not allow to incorrect reading.

Always try to standardize you electrode with the ref electrode to see any irregularity and it is easy to check. With damage electrode, your readings would be incorrect giving erroneous conclusion in your research.
