How do I match electrodes to housings?

Download FAQ

Housings and FermProbe® pH electrodes are offered in a variety of lengths. This enables fermentation operators to select the optimum insertion length for the application at hand. The housing ordering information box lists the suitable electrode models and lengths for each particular housing style.

There is another way to match electrodes to housings. Each housing length is given a letter classification, i.e. “A”, “B”, “C”. Each electrode length is given a similar letter classification. Any Class “A” pH electrode will fit any Class “A” housing listed in this catalog. Similarly, any Class “B” electrode will fit any Class “B” housing. By matching the classifications, the electrode and housing will match.

The class information is found in the ordering information box for any electrode or housing in this catalog. If the class letters are the same for any electrode and housing then the two can be used together. See the illustrated example below:
