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.

As with all methods of testing, it has its limitations. The advantage is that you can test very valuable items such as rare coins which must not be marked in any way.

PLEASE NOTE, THE WEIGHING MACHINE IS NOT INCLUDED,

YOU WILL NEED ONE THAT WEIGHS DOWN TO 0.001g. (recommended: CT-250)

 

IS IT THE RIGHT SIZE?

Will the attachment fit the scale?

The height from the top of the base to the circle that holds the beaker is 165mm. 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 3mm thick.

Alternatively, if the scale is very small, it can stand on top of the base. The base measures 130mm X 80mm

The distance from the upright (pole) to the middle of the flask (which should line up with the middle of the weighing platform) is 130mm

You can use a scale requiring a shorter distance but not a longer distance.

What is the largest-size item that can be tested?

The diameter of the platform on which you place the sample is 25mm and the beaker gives you a height of about 45mm.

In practice, an item this tall and thin would fall off the platform; in practise, the largest size would be the equivalent of a stack of 4 or 5 one-pound coins.

Too small? There are dedicated balances (densimeters) instead of an ‘attachment’, prices are usually about £2000.00 to £3000.00 but see our special clearance prices..
