An Update from the Sigma Metalytics Team:
Precious Metal Verifiers are now being widely
used in the United States (View items here). The positive feedback we have been
receiving from dealers and their customers is great, and has provided us with
valuable information. This data has been used to further improve
the abilities of the PMV in detecting fake or counterfeit metals.
BULLION METAL CHOICES UPDATED AND IMPROVED
We were recently informed that a 10 oz. PAMP gold bar with a
5 mm thick plate of tungsten in the middle was discovered by a dealer in New
York by other methods than the PMV. In order to improve detection
on these counterfeit bars our gold bullion scale has been updated to check for
.9999 gold on a narrow range. This increases the Precious Metal
Verifier’s ability to detect tungsten underneath the gold.
The new Metal Data is on the website www.sigmametalytics.com.
Click on the details tab and under Latest Software Updates select the
Metal Update PDF. It provides instructions for updating the categories on
the PMV to increase the sensitivity of the bullion range.
If the User Guide Addendum in your manual is dated October
2015, then you already have the new update on your units and won’t need to make
any changes.
IMPROVEMENTS TO GOLD METAL CHOICES
Gold-Krugerrand is now a choice in the Gold category.
The Gold-Krugerrand listing is the same as Gold-91.7% 22K balCu scale and has
been added to assist users who are unfamiliar with the numerical metal content
of the Krugerrand.
CLARIFIED SILVER CHOICES
Earlier this summer we relabeled the Silver 90% categories
to Silver 90%US pre1900, Silver 90%US pre1945, and Silver- 90% Coin 1960 (for purer
90% Ag 10% Cu coins). By following the procedure for updating the
Bullion Metal Choices, you will also update the PMV to the latest listings for
gold and silver choices.
IRON CONTAMINATION IN GOLD
Iron contamination in gold will affect the PMV reading. The
ASTM standard B562-95 specifies the amount of iron and other metal impurities
allowed in refined gold for a given purity. If gold meets this standard,
it will show as consistent with gold on the PMV.
Keep up the good work,
The Sigma Metalytics Team
