PRESIDIUM Synthetic Diamond Screener II (SDS II) Tester CVD HPHT D to J Color

Description

Synthetic Diamond Screener II (SDS II)
Enhanced with additional features, the Synthetic Diamond Screener II now tests for diamond melees as small as 0.02 carats with instantaneous results, through the measurement of UV absorption.
The Synthetic Diamond Screener II is developed by Presidium to help screen out Type IIa colorless diamond, which is likely to be synthetic and created through chemical vapor deposition (CVD) or high pressure high temperature (HPHT) syntheses, from the natural Type Ia colorless diamond.
When subjected to this deep UV irradiation, Type Ia and Type IIa diamonds each absorb different amount of UV light. Type IIa diamonds allow deeper UV light to pass through and thus its UV light absorption ability is low. This difference in the light absorption is significant enough to aid in differentiating between colorless Type Ia and Type IIa diamonds.
Features
Advanced technology that measures a diamond’s UV light transmittance ability
2 colour coded (blue/red) indicator light bars to give a low or high reading of UV light absorption with blue light indicating Natural Diamond and red light indicating Type IIa Diamond
Instantaneous clear results within 2 seconds
Blue light to illuminate the testing pad
A 5mm metal bar to conveniently raise the test probe for successive testing on loose stones
Test button will blink in red to alert if the device is unable to detect any stones on the photo-detector
Auto shutdown of interior LED light source for safe testing when lid of device is open or when Start Test button is not activated
USB port for alternative power source and connectivity
Exterior base foam padding to ensure non-slip sturdiness and prevent scratches to surfaces
Low battery indicator
Energy-saving auto power-off of device after 10 minutes without operation
