Hydro Testing Equipment Maintenance – How to Clean a pH Electrode


It doesn’t take long for buildup to form
on the sensing bulb, and this build up creates a barrier between the glass and sample, causing
inaccurate readings. Cleaning with deionized water alone will not
remove the coating of some organic and inorganic materials. What you need are appropriate Cleaning & Storage
Solutions. To properly clean your electrode, soak the
sensing bulb and reference junction in the cleaning solution for 10 to 15 minutes. Cleaning solution helps to remove any materials
that water alone can’t. After, place the electrode into your storage
solution for 2 hours to rehydrate the glass bulb. If you’re using a meter or tester that uses
a cloth junction, take the added step of pulling the junction out 1/8 of an inch and cutting
the old end off. Simple tools like tweezers and nail clippers
are all you need for this step. To ensure the life of your probe, after it
has been cleaned, put some storage solution in the electrode cap, and keep it on until
the next use. For a list of best practices for pH electrodes,
