I went to Takapuna today to get some nsw,
this is the second time ive tried nsw, first time i went to Murawai.
I have a swing arm type hydrometer, and when i mix up asw, i mix it to about 1.024.
I have tested Takapuna water today and it reads 1.021 , as i understand its usually around 1.028. So if takapuna water is 1.028 today, my swing arm type hydrometer is way off, which i understand is not uncommon.
So my next question is, should i put the NSW straight in, even though it reads 1.021, im a bit worried about lowering s.g to fast.
I was thinking about buying a floating type hydrometer, are they any better than swing arm?
I would love to get a refractometer but dont have the funds at the mo.
Thanks in advance
