Neptune Systems Double Junction Lab Grade pH Probe
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.

Excellent accuracy and response.
This one Neptune got right. This probe holds calibration very well and responds very quickly, maybe too quickly since I often get pH alerts when my alkalinity doses. It closely agrees with my handheld pH meter. I find it quite useful in determining my dosing schedule. I won't hesitate to purchase this probe again when the time comes.
