Neptune Systems Double Junction Lab Grade ORP 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.

Works as expected.
I don't know how important it is to measure ORP if you're not running ozone, but this probe reacts quickly and I've never had a reason to doubt its accuracy. If you are running ozone, I would probably double check against another ORP meter to be safe before trusting it to control the ozone generator. My tank reads in a pretty narrow range that is mostly consistent with rises and falls of pH (inversely correlated), that's good enough for me.
