I'm no atheist scientist, but...
So, i've decided that my hydrometer is garbage.
Can anyone recommend a decent one?
Can anyone recommend a decent one?
i have a few complaints about this one:
1st, and this might be my ignorance, it says on the piece of paper it's calibrated at 68F. But on the actual hydrometer it reads "Sp.Gr. 60F / 60F". Doesn't that mean it's calibrated at 60F?
Also, do i read the upper meniscus? In distilled water especially, the different between the lower meniscus and upper is about 5 points. Also, the "climb" of the upper meniscus accounts for about 2 points. So i'm not sure if i'm supposed to read the top of the meniscus or the top of the climb.
They cost 25 if you have an account. So 10 bucks more than the LBHS POS ones. Well worth it for something you can trust. And besides, I'm a chemical engineer by trade so I can't justify saving 10 bucks for a hydrometer you have to check the value against a correction table to get the correct value every time.
