Traditional acid checks and basic density methods fail against sophisticated multi-layer electroplating and toxic PGM adulterants. Fishtro combines precision Korean X-ray sensor architecture with localized Indian hardware resilience (`CFAN Technology`) to deliver non-destructive, certified assays in seconds.
Every KaratVision spectrometer (`K2, K3, K4, K5 Series`) is built with verified technical specifications extracted verbatim from official diagnostic sheets, eliminating guesswork and costly assay errors.
Unlike outdated Si-PIN systems or liquid-nitrogen cooled detectors, our advanced Fast Silicon Drift Detectors (`FSDD`) operate with thermoelectric Peltier cooling. This achieves state-of-the-art energy resolution (`<118 eV to <145 eV @ 5.9 keV`), enabling count rates up to 1,000,000 cps without thermal drift.
✦ Specification: K3, K4 & K5 SeriesBullion fraud often involves alloying gold with trace Iridium (`Ir`), Osmium (`Os`), Ruthenium (`Ru`), or Tungsten (`W`), which mimic gold's density. KaratVision algorithms perform automatic quantitative separation of trace PGM adulterants down to `<100 ppm` instantly during standard testing.
✦ Specification: <100 ppm to <200 ppm Trace DetectionAccurately estimate up to 5 overlapping electroplated metal layers without scratching, filing, or acid etching. Verify top gold flash (`Au 99.9%`), nickel barrier substrates (`Ni 0.50 µm`), and base sterling silver (`Ag 92.5%`) down to `0.01 µm` depth capability.
✦ Specification: IS 2112 Plating ComplianceTesting tiny filigree wires, soldered earring posts, and micro-prongs requires pinpoint X-ray isolation. Our dual and quad motorized collimators (`0.1 / 0.3 / 1.0 / 3.0 mm`) paired with 20X/40X HD Macro cameras ensure the X-ray beam hits only the intended sample spot.
✦ Specification: 20X Zoom Alignment & Auto-FocusDesigned specifically for Indian Assaying & Hallmarking Centers (`AHC`), bullion mandis, and retail showrooms. Pre-loaded Fundamental Parameters (`FP`) and empirical curves verify exact karatage (`24K, 22K, 18K, 14K`) strictly conforming to BIS `IS 1418` national standards.
✦ Specification: National Hallmarking GradeIndian jewelry markets demand rugged continuous operation under elevated temperatures and power fluctuations. Powered by a Micro-Focus Tungsten tube (`50 kV / 100W`), our solid-state metallic chassis provides superior electromagnetic shielding and 24/7 reliability.
✦ Specification: 110-240V AC • 100W Low PowerFishtro Instruments unites high-precision Korean X-ray sensor hardware (`CFAN Instrument collaboration`) with robust Indian manufacturing and direct factory calibration support. This dual synergy guarantees uncompromised analytical speed alongside responsive, local technical service.
See why modern bullion refiners, jewelry manufacturers, and national assay labs are upgrading from acid testing and first-generation benchtop devices.
