Well, atleast my son was happy to have a new addition to his toys - my hydrometer. Its clear , has numbers and moves on tickling. Good for a playing child.
I always doubted my hydrometer for accuracy. Took it to the LFS where I purchased and he told me it was perfect, though he did not check it with his refractometer. Took it to other shops, Readings were off scale.
FInally took it to the beach and took reading using real ocean water - Shows 1.018 That was the end of it and my son had a new toy.
Now going to get a refractometer. The prices are rocketting in India and so decided to source it through friends in US. I need help from experts on the type of refractometer to buy. Tried in amazon and got a ton of results. They have some specs related to it which I guess is the salinity(0-10%, 0-28% and 0-100%) and ATS for auto temp comp... Not sure which is required for our use. I do not require a ultra precise equipment costing a bomb. All I need to get is +-0.001 accuracy.
Any links would be appretiated.
The cheaper Chinese/Hong kong based refractometers are sub 2x $ and they give ph meter free with it(probably both are not moving products). Vertex has one for 4x $ which looks reasonable.
