Read MoreWhy switching from traditional destructive fire assaying and chemical tests to Fishtro KARAT VISION XRF pays for itself in months while protecting your precious metal assets.
Instant non-destructive verification of gold purity Au 24K, 22K, 18K down to 9K without waiting hours for acid bath results or scratching ornaments.
Zero material destruction, zero drilling scrap, and zero toxic chemical fumes. Protects 100% of ornamental resale value and customer trust.
Direct adherence to Bureau of Indian Standards IS 1418:2009 gold assay and IS 2112:2014 silver assay reporting protocols across Indian showrooms.
Eliminates external testing charges, prevents buying under-karated scrap jewelry, and increases daily customer footfall through instant certification.
Engineered with micro-focus tungsten tubes (50kV), bottom-to-top unique geometry, CCTV 20X zoom cameras, and dedicated Peltier cooled detectors for instant Gold & Silver classification.
Advance FSDD PRO+ superior technically, supported locally. Optimized for lowest detection limits (<122eV) across gold, silver & PGM alloys.
Fast and accurate non-destructive analysis of gold jewellery, hallmarking ornaments, coins, and alloys. Uses reliable FSDD cooled technology.
Engineered for high-speed sterling silver (Ag 925/999) verification, bullion classification, and dependable daily measurement across showrooms.
What’s Distinctive: Unique measurement geometry at an accessible entry-level price. Ideal for growing jewellery showrooms and pawn brokers.
"It’s so good in the last 3 years the KARAT VISION gold and silver testing instrument has paid for itself."
"We chose the KARAT VISION K5-Series to have a cost-effective, ultra-high resolution solution to analyze gold purity and rhodium plating."
"We've chosen Fishtro products because of their extremely good price per performance ratio, they're very user-friendly, easy to use and maintain."
"We've been very happy with Fishtro equipment because they are robust, easy to use, easy to set up and calibrate, and they are reliable."
Discover our latest installations inside commercial jewelry showrooms, central assaying laboratories, and BIS hallmarking facilities across India.
Active deployment inside a high-volume bullion assaying center. The dedicated workstation features our instant touch-screen UI, providing 8-second karat classifications and continuous batch LIMS data reporting.
Integrated directly onto retail showroom sales counters. Compact bottom-to-top chamber geometry allows jewelers to perform transparent buyback verifications in front of customers with zero noise or vibration.

Precision micro-targeting inspection at an accredited hallmarking facility. Using motorized quad-pinhole collimation (0.1mm to 3.0mm), operators isolate delicate ornament prongs and generate tamper-proof digital certificates.
Everything you need to know about non-destructive XRF spectrometers, gold verification accuracy, and localized engineering support.
Fire assaying (Tunch) is destructive, requires melting the ornament, consumes hazardous chemical acids, and takes 3 to 6 hours to yield results. Fishtro KARAT VISION non-destructive X-Ray Fluorescence (XRF) tests the ornament completely intact in less than 10 seconds, with 99.99% analytical correlation to fire assay and zero metal loss.
Yes! Our advanced FSDD PRO+ detector series (K5 and K4 models) feature proprietary multi-layer plating depth analysis algorithms. They accurately identify gold vermeil thickness, rhodium coatings on white gold, and instantly flag under-karated substrates or counterfeit tungsten/copper/brass cores without scratching the surface.
Silicon Drift (FSDD PRO+) detectors offer ultra-high resolution (<122 eV) and count rates up to 10X faster than standard Silicon PIN (<160 eV). While K2 (Si-PIN) is excellent for standard karat sorting in growing showrooms, FSDD PRO+ is essential for rapid hallmarking certification, complex PGM alloy separation, and measuring trace impurities down to 0.01% precision.
