First step is to take the weight of the sample on the air table of our analytical scale. Let's call it weight in air.

Based on the Principles of Specific Gravity (Density). Density is the substance’s mass per unit of Volume. For a Pure substance, the Density has the same numerical value as its Mass concentration. Different materials usually have different Densities, and Density may be relevant to Buoyancy and Purity . Osmium and Iridium are the Densest known elements whereas Gold follows them. Specific conditions for Temperature and Pressure are required to measure it. The Density of a material varies with Temperature and pressure. Increasing the Pressure on an Object decreases the Volume of the object and thus increases its Density. Increasing the Temperature of a substance decreases its Density by increasing its volume.
First step is to take the weight of the sample on the air table of our analytical scale. Let's call it weight in air.
Second step is to take the weight o f the sample in beaker filled with liquid. Let's call it weight in liquid.
Third step is to feed both of these weights in our mobile application in theiris to take the weight o f the sample in beker filled with liquid. Lets call it weight in liquid. respective fields.
Hit the check gold purity button to find out the purity of gold in the sample.
Note : Hollow and stone studded jewellery won’t be checked.
We use high accuracy weighing scales with 0.0001 density resolution, which provide high accuracy in lite weight samples too.
Our application also supports testing of jewellery having AD stone & diamonds.
There is a special feature in our application for testing jewellery items with hollow balls (Goli).
Emfc (electro magnetic compensation force) technology is used in our analytical weighing scale, which ensures accurate repeatability of weight & durability of the machine.
Our application shows results in carats as well as percentage.
PDF report of the testing can be generated in single tap for easy sharing
We offer a wide range of opportunities for you. see what you will get and your benefits
No radiation is involved in the density meter, thus making them safer to use without any specific precautions.
Density meter have very low to zero maintenance as its analytical instrument is just a weighing scale and it does not require any maintenance.
It’s the only density meter that can calculate the gold content in the complete sample thereby making it possible to find out the gold purity in bandhel jewellery or gold plated jewellery.
XRF machine just checks the upper layer of the sample till 200 μm (0.2mm), whereas the density meter calculates the purity in the complete sample; not just the skin.
Density meters are smaller in size, thus making them more convenient to handle and operate.
To make it convenient for the jewellers, the density meter is designed in such a way that it just costs a fraction of the XFR testing machine price.
ery excellent accuracy of this gold testing machines. God bless you and grow your future
I have been using this machine for 2 years, it's up to the mark as it my opinion… you should to buy it…
Very convenient to use with no maintenance cost. Accuracy is correct! totally worth it!
