How do you clean a Hanna pH probe?
General Cleaning Procedure For general cleaning, soak your pH electrode in the HI7061L General Purpose Cleaning Solution for at least 15 minutes. Then rinse the electrode with water before allowing it to rehydrate in HI70300L storage solution for at least one hour (overnight for best results).
Why is it important to never touch the glass bulb at the end of a pH meter?
Because what the pH meter is actually measuring are tiny, tiny changes in electrical potential. If you wipe the surface of the bulb, you can induce a tiny static electrical charge on the surface of the glass. Though minuscule, this static charge can be large enough to throw your readings off.
