Dissolved Oxygen Meter Questions

[ba-brewer]

The price of a DO has had me dragging my feet in buying one and the fact most of the early LODO post seem to say folks stopped using them after a short time did not help. I was looking at the low end Milwaukee MW600, @Schlenkerla posted information on his smart sensor DO meter what seems to be a nice lower cost solution to bigger name brands. At about $100 from amazon this close to half the price.

I like the price but can't seem to find replacement membranes. I see the name brands have replacements for about half the price of the smart sensor but I think they are interchangeable. Beable to get replacment membranes seem like an important feature.

How important is being able to get replacement membranes?

I see the smart sensor has the ability to save altitude information and salinity information where the milwaukee MW600 does not.

How important is altitude and salinity to brewing if you will be using the meter in one location?


Some of the smart sensor meters don't come with electrolyte solution, can you use solution from other vender?

The "spare protective covers" include membranes within; I wonder if you could use a different make/model on that sensor?
Don't know about the electrolyte, perhaps whatever works in an MW600 will work...

Cheers!

[edit] That same meter is sold under at least three different names on Amazon, and this one includes electrolyte.

I think the electrolyte solution for meters using the same measuring principle should be compatible but I just don't know for sure.

Finding a cap/membrane that fits correctly seem very important as you would not want to leak electrolyte solution in your beer. An improper fit would also make the measurements questionable too.
