The **K4-Series** utilizes an advanced **Fast Silicon Drift Detector (FSDD)** coupled with Peltier thermoelectric cooling and a programmable 50Kv Micro-Focus Tungsten Tube. This ultra-low noise architecture achieves < 122 eV energy resolution, allowing exact separation of overlapping X-Ray fluorescence peaks across all elements from **Sulfur S (16) to Uranium U (92)**.
Result: Instant detection of trace hazardous adulterants like **Cadmium (Cd)**, **Nickel (Ni)**, and **Lead (Pb)** down to parts-per-million (ppm), ensuring zero rejection during BIS hallmarking audits.
Yes. The **Fishtro KaratVision K3-Series SDD (< 145 eV)** is specifically optimized for multi-phase testing including **Solution & Powder Analysis**. Using dedicated sample cups and specialized calibration curves, refiners can directly quantify exact gold (Au) and silver (Ag) concentrations in acid recovery baths and workshop dust (Kachra) without wet chemical preparation.
It also instantly flags rarer precious metal adulteration by **Osmium (Os)**, **Iridium (Ir)**, and **Ruthenium (Ru)**.

You can call our direct support helpline at +91 97018 98855 to book a visit or schedule an on-site demonstration across our national hubs (New Delhi, Chennai, Kolkata, Bangalore, Hyderabad, Surat, Indore).
Absolutely zero physical damage. Unlike touch-stone acid testing or destructive fire assay cupellation, Fishtro KaratVision XRF spectrometers use a high-resolution 20X CCTV camera and a fixed 1.0 mm micro-focus pinhole collimator to target exact spots on jewelry, bullion, or ancient museum artifacts.
The ornament is irradiated with low-power X-Rays (50Kv, 100W), and the secondary fluorescence is analyzed in 10 to 15 seconds, preserving 100% of the item's weight and luster.
