What is the recommended PH probe to use with the robotank v3?
I see some with decent reviews that are cheaper...not sure on reliability. https://www.amazon.com/Electrode-Socket-...358&sr=8-6

A couple weeks ago I had to order a new probe, as I don't really use it I wanted to save a few bucks and ordered the type you linked to. It did calibrate fairly well but I noticed the readings weren't as stable as my previous probe. These probes are single junction probes where my previous was a double junction probe which is an extra layer over the bulb in the probe. I'm not sure if that's the reason for less stability but I've read that double junction are recommended and do last longer. Here's the one I had previous.
