{SUMMARY}

Weigh the item on a very sensitive weighing machine (down to 0.001g is recommended).

Then weigh it again, but this time suspended in water - that's what the specific gravity kit is for.

Now find a calculator and do a simple calculation.

Disadvantages: setting up the equipment takes five minutes; after that, each test takes five minutes. And you need to do some (albeit simple) arithmetic and look up a chart. None of this is difficult, but it is not 'electronic' or 'digital' or 'instant'.

Advantages: you can test very valuable items such as rare coins which must not be marked in any way. You can also test a large variety of materials including metals and gemstones.

PLEASE NOTE, THE WEIGHING MACHINE IS NOT INCLUDED,
YOU WILL NEED ONE THAT WEIGHS DOWN TO 0.001g.

{WILL IT FIT YOUR SCALE?}

The height from the top of the base to the circle that holds the beaker is 140mm. You can make it as lower, but not higher.

You will also need to slide the base underneath the scale. Ideally, this will require a gap under the scale. The base is 2mm thick. Alternatively, if the scale is very small, it can stand on top of the base, the base measures 100mm X 65mm

The distance from the upright (pole) to the middle of the flask (which should line up with the middle of the weighing platform) is 100mm. You can use a scale requiring a shorter distance but not a longer distance.
