Is my ph probe damaged?

[Dodgersfan]

hey guys, I bought a used apex off of eBay I’ve had it for a while, Isn’t the probes up on a spare tank to keep them wet while I was waiting for my tank to be ready. I didn’t pay too much attention to the readings, but when I was moving it to the main tank I noticed something that is either a crack in the inner tube, or possibly a Filiment wire that is supposed to be there, I’ve also noticed a small amount of liquid inside the probe. Here’s pics and a video hopefully you can make it out. I’m thinking it’s busted but wanted to confirm before dropping coin on a new one... I’d test it on the tank and see what it reads, but if it’s broken and could leak something dangerous into the tank I don’t want to put it in. Thanks for the help.

Is it calibrating?

It didn’t come with fluid, I’ll have to order some. I could stick it in the tank and compare it to my Red Sea test, just wanted to make sure it was safe to stick in the tank before doing so.

If it's not leaking worth a try. Anyway the membrane/ glass is semi permeable

Alright, will give it a shot and report back

Red Sea kit says 8.2. Probe says 8.98

So should I replace it? Or does it just need to be calibrated?
