My thoughts were definitely based on my own assumptions - optics mounted to metal, metal expands or contracts, optics move with it, reading becomes inaccurate.

That link is in my favourites, so obviously I read it and saved it once before.
Not to be devil's advocate but considering that we're peering through a sliver of water, it seems to me the water temperature would quickly become the temperature the refractometer is, and as long as the device was consistently the same temperature, the sliver of water and it's temp would become a non factor. Not arguing, just thinking.
I actually like glass hydrometers and was disappointed when the local LFS didn't have it.The tropic marin precision glass hydrometer is $31 and blows everything else away. Far more accurate and precise. Don’t scoff at the idea of using a hydrometer... this one is very different than the old plastic swing arm pieces of junk.
I will likely upgrade to the Hanna, but I have the cheap amazon one and it works fineHello,
My LFS has a refractometer for $70. I see on Amazon that there are some for $20. Should I be leery about the cheaper price tag? Could they be junky? Thoughts?
FISH ON!!,
BUM
