How to pass salinity (or pH) probe into sealed ATO container? Bulkhead?

[drtechno]

Hey all. If I have a salt water container or ATO (Norwesco tank), and I want to keep it sealed, how do I go about passing an Apex probe inside it? I can drill a bulkhead or hole in the top, but then what? Is there a rubber skirt type thing that I can put inside the hole that I can just push the probe thru, and down into the tank? Not sure what to even call the part? A sealing gasket??

Let me know.

You just need something like this:

Reef Fanatic Probe Holder Bulkhead

This is a probe holder that will hold the majority of PH and ORP probes. American Marine, Pinpoint etc. You can use it to install a probe into a reactor (i.e. Calicium) or sump. Simply drill a hole, install the bulkhead, and then insert the probe and tighten the holder down around the probe...

thanks. That’s one option. But if I’m dropping through the top of a 5 foot water container down to the bottom, I’ll need something else that is big enough to push the probe through but then will close up behind it. Doesn’t need to be water right as I’m just preventing splashing and evaporation mostly.

I had a loose connection on my saltwater mixing station that I plugged with two-part epoxy. It took a couple attempts because it was under pressure, but it worked.
