What is XRF? X-ray fluorescence explained

This hand held XRF machine is so handy and it’s really creates peace of mind when buying second hand jewellery or branded jewellery. A lot of the branded jewellery in the market place is fake and often it’s tricky to spot. This machine analyses the metal content of the jewellery and gives a breakdown of the composition of the metal. It even highlights if it maybe plated so you can take it for further tests. Before this machine we would have to carry out a slightly destructive acid test. Amazing!
