Specific gravity, or, what does"please enter a descriptive title for your question "mean?

0 votes

I was hoping to see if there was any chat, "first hand", about what people used to determine specific gravity. Ohaus makes a mechanical scale that measures down to the hundredth of a gram, which would seem to be sufficient. It only goes to 331grams, I think...I would like 3-4 lbs., and I would really like to stick with a mechanical unit. I do not mean to be trite with the title, just have a hard time doing stuff according to hoil. ....and understanding what to do in the net....shouldn't there be a dip-thingy over "your"?

A lot depends on what you want to find the Specific Gravity of.  If you are looking for 3-4 lbs. Then digital scales with accuracy to 0.01g is suitable.  However, if you just want mechanical scales then you increase your work significantly because the triple beam means setting three sliders to find balance.  Also you need to find a suspension scales not the Ohaus.  Unless you suspend the article to be determined in your fluid.  The upshot is that it is more complex and time consuming.

I would recommend the use a digital scale with an underhook capable of taking 2Kg and 0.01g accuracy.  although you can use the displacement method from top of the scales.
