You think? But you are assuming the writer knows what he's talking about.
I'm often ridiculed for the instrument I use, but at least I don't have to describe it with untruths and down-right fibs. So, because I'm ridiculed, I'm going to tear this awful article to pieces ...
First untruth ... "
Hydrometers use density to measure the dissolved solids ...". No they don't, they use buoyancy. Density is mass divided by volume. To use a hydrometer, you neither weigh the specimen nor measure its volume.
Next untruth, or in this case deceit (fib, white lie, whatever you'd like to call it). And it's the one key to this query: "
Hydrometer readings can also be skewed with carbon dioxide dissolved in solution. Whether the beer has just finished fermentation or the beer has been carbonated, carbon dioxide is going to lift the hydrometer up in the cylinder and give a false reading. ...". Read it carefully. It actually
is saying that bubbles forming on the hydrometer are skewing the reading just like the guys here have been telling you. But it's written to give the impression dissolved CO
2 is what's skewing the measurement. Smoke and Mirrors, for what gain I don't know. Carbon Dioxide bubbles create buoyancy, hydrometers measure buoyancy. If I was
@foxy I'd be pretty peeved being drawn into that deceit.
Enough! I could go on, but I think two blatant, key, errors are enough to discredit that article.
