What's the difference between double junction and single junction probes?

Single junction probes put the reference electrode in direct contact with aquarium water. Over time, the junction will slowly leak aquarium water into the electrolyte which changes the accuracy of the probe and requires more frequent calibrations.

Double junction probes place a second vessel inside the main electrolyte with a second internal junction. The means that even when the aquarium water eventually begins to make its way in the first compartment, it still has to go through the second junction to contaminate the electrolyte surrounding the reference electrode.

Double junction probes are they way to go, they last way longer then the standard ones. Splurge the extra few bucks for the lab version

Advantages: Works well.
