A quality conductivity probe

[Rocks reef]

Randy,

What would you recommend for a good conductivity probe? I know you have mentioned using one as they are quite accurate, however, in the searches I've done. I don't remember actually seeing a name of one you use. You did mention Orion, but they are out of business if I recall.

Thank you for your time.

I've not bought a new one, ever, since good ones are fairly expensive.

There are a number of good old and new high end brands. Orion was the gold standard years ago, and I used one of those for 20 years, but it died (the long cracked probed finally broke in two) when I started my new tank.

I recently bought an old VWR conductivity meter on ebay, and I'm happy with it, but they don't come along all the time.

Rishma recently got this one:

The main thing to be sure of if getting a new high end meter is that it has a probe designed to measure in the 53 mS/cm range for seawater. Some are specially designed for much lower conductivity.

Thank you sir, I appreciate you!

FWIW, your post made me look at the picture of my probe I posted in my Tank and Learn thread, and it is really strange:
