Gold, watches and jewelry
Non-destructive and reliable coating thickness measurement and material analysis of precious metals.
All that glitters is not gold. Particularly for the gold, watch and jewelry industries, reliable and accurate measurement technology is indispensable for testing the authenticity and purity of various precious metals. A purely visual sample is usually not enough to be certain. Traditional techniques like Assay, while effective, are time-consuming and destructive, preventing immediate results.
Don't be deceived by appearances. Rely on Fischer measuring instruments! Our product range offers non-destructive measuring methods for coating thickness measurement, material analysis and material testing of precious metals.
Application examples
Especially for the purchase and trade of precious metals such as gold, silver, platinum or titanium, Fischer has developed non-destructive and absolutely reliable measuring devices with which you can decipher complex decorative coatings in seconds, detect the finest differences in precious metal alloys and determine the purity of the precious metal from gold bars to coin gold to fine gold.
Are you possibly dealing with counterfeit goods? Play it safe and rely on our amplified measurement technology for the gold and jewelry industry.
Application Notes
Are you in the watch business and work with decorative or functional coatings on watch components such as cases or dials? Do you want to rely on many years of expertise and well-founded measurement technology to ensure the quality and longevity of your watches? After all, a watch in particular is exposed to high wear and tear and, at the same time, strong temperature fluctuations by being worn on the wrist – from body temperature and intensive sunlight to the effects of the weather in frosty winter temperatures.
When coating with PVD, CVD or precious metals, it is not only aesthetics that play a decisive role, but also properties such as dimensional stability, lightness or scratch resistance. Fischer measuring instruments allow you to non-destructively test the thickness and composition of the thinnest coatings, thus ensuring the quality of your watches.
Application Notes
In the jewelry industry, complex multilayer systems are often processed for cost reasons as an alternative to conventional nickel alloys for fashion jewelry and accessories. The focus here is particularly on skin compatibility in compliance with legal regulations such as INMETRO Ordinance No. 43/2016, which prescribes strict limits for harmful substances such as lead and cadmium. In order to comply with safety and health standards, it is essential to thoroughly and carefully test the quality of the material compositions and layer systems.
Fischer offers suitable equipment for this purpose as well as powerful software solutions for a wide range of measuring tasks in the field of fashion jewelry.
