pH meter Use
pH meter Use
(OP)
I have a question reguarding the use of a desktop pH meter, The meter I am using comes with a BNC cap that shorts out the input to the pH meter, but I have to remove the cap to use a pH electrode to make measurements, what is the cap used for? and when would I use it?





RE: pH meter Use
Considering that DI water is at 18 megohm-cm, one can imagine that the pH meter input is very high impedance and susceptible to static damage.

Have used all sorts of benchtop and portable pH meters in academic and industrial settings, and never heard of ESD being a problem. Not mentioned in Corning or Fischer manuals, either. High humidities, corrosive atmospheres and sloppy users were sometimes a problem.
