Built for jewelry professionals and assayers, it delivers precise elemental identification with a high-resolution Silicon PIN detector—offering approximately four times better element separation and lower detection limits than standard proportional counter systems.\n\nKey specifications include a bottom-to-top X-ray configuration with a tungsten target tube operating at 50kV, measurement times of 15–180 seconds depending on sample type, and X-MasteR software supporting both empirical and fundamental calibration modes. Pre-calibrated for gold analysis, the system works seamlessly on solids, liquids, and powders without sample preparation or destruction.\n\nIdeal for jewelry workshops, assay labs, and quality control environments where speed, accuracy, and non-destructive testing are essential.","brand":"Aczet","offers":[{"title":"Default Title","offer_id":52736919732405,"sku":"Aczet® Stark Pro Pin - XRF Gold Testing Machine","price":17000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0251\/1947\/files\/IMG-20260624-WA0040.jpg?v=1782333065","url":"https:\/\/zakjewelrytools.com\/products\/aczet-stark-pro-pin-xrf-gold-testing-machine","provider":"DECOZE JEWELRY TOOLS","version":"1.0","type":"link"}
