Gold and Silver plating

he Karatmeter is a scientific device which uses X-rays to give an exact reading of the purity of gold. Due to its excellent precision, X-ray analysis has been adopted by international agencies in India as part of the certification process used to hallmark gold. It is an accurate, non-destructive means of testing the purity of gold and other related elements.

Using this technique, the precise percentage by weight (of karat) in a solid piece of jewellery can be determined in just a few minutes. It also accurately determines the element composition of all types of gold, white gold, platinum, silver, palladium, rhodium and related alloys.

Home Why Tanishq Tanishq Gold Karat Meter

Karat meter is technically called X-Ray Fluorescence (XRF) Spectrometer. Tanishq named it as karat meter for easy understanding to customers.

The analysis of gold in gold jewelry alloys has been performed during the last thirty centuries by the cupellation or fire assay method. Although it is the most accurate technique it is also destructive. The touch stone method has been there for centuries but is not an accurate method of testing gold. Its accuracy is dependent on composition and colour of alloy, quality of touch stone, strength of touch acid, lighting conditions and operator skill. The test is not suitable for very high karat gold or hard white gold.

What then are the benefits of using a Tanishq Karatmeter?

It offers non-contact and non-destructive testing. Sample material is not consumed.

It is extremely fast. Measurement takes only minutes, and results are obtained immediately.

It can identify all elements in the sample and their respective weight percentages (composition)

The results are operator independent, so different people using the system will get the same results.

X-ray assay is NIST (National Institute of Standards Technology) traceable and confirms with ASTM B568 and ISO 3497.
