Milwaukee SMS122 PH Monitor/controller - $50

[estanoche]

I bought a formal controller system for my tank, so I don't need this little guy anymore to monitor my CA reactor

No probe, as it is 100% better for you to buy a new one, and my old one is totally disgusting and way outta calibration!

Any BNC ph probe will work, and they run maybe $20 from most stores

I'll ship this to your door for only $50 Great deal if you were looking for one of these - this thing is literally new - I've only had it for 2 years, and I kept it in a clean, dry electronics cabinet so no salt creep whatsoever
