PH Probe Replacement

[bluprntguy]

Seems that my PH probe has a crack in it and is leaking voltage into my tank, so it needs to be replaced. It looks like the BRS probe has the same connection as the GHL PH probe. While the cost difference is minimal, I'd rather not add shipping for one probe from GHL. Does anyone know definitively if I can use the BRS probe (or any probe for that matter) with the Profilux?

Stray voltage from a probe?
Is that a thing?

That does sound odd. How do you know the voltage is coming from the pH probe? And if you are measuring it, how much?

Seems like that is how they work. I guess I should be more careful. I’m sure I damaged it while cleaning the sump.

Process of elimination over many months. Also, you can see there is a crack in the glass around the probe and it hurts when you stupidly touch the end of the probe.

I noticed tingling sometimes when I put my hand in the tank. It felt like when you put a 9 volt battery on your tongue. Tested with a multimeter and it was 5-6, which isn‘t high. I kept searching though to figure out what was wrong.

i think if it has the same plug it should. I am using a Tunze one on mine.

Learn something new every day, thanks.

Thanks for the info. Never heard anyone ever having an issue such as this. I'm sure it would help others battling the same problem with stray voltage.
