Is there any accuracy advantage to double junction electrodes over single junction electrodes in brewing applications, or is it just a longevity issue?
I can get 2 of these:

for the about the price of a low end double junction. Assuming the single junction lasts 6 months and a double for 12 months; if accuracy is similar the cheaper single junction seems to make sense.
I will be using it with this meter, and will brew at most 2x per month:
