Suitable pH electrode

I use a couple of check points when I choose my pH electrodes. It has of course happened that I picked the wrong electrode type. Well, then I have learned something new. . . Experience is the best teacher.


My check points to identify a suitable pH electrode:

• Application. For what application will you use your pH electrode? Most supplier of pH electrodes also provides a pH electrode selection chart. The selection chart will probably give you a couple of choices for different applications.

Check the proposed electrodes with respect to:

• Temperature.

• Pressure.

• pH Range.


Good luck!
