hey everyone rich from mygold here
really excited today to give you guys a
quick demo of this
fantastic device called the gold spring
screen box
made by some very very very smart
scientists
out of germany which i saw uh in berlin
earlier this year
um as you'll be aware testing of
precious metals there's no
um one method that's perfect for testing
any kind of
coin or bar and every every method
effectively has its limitations or
downsides
for example with xrf is going to give
you a highly accurate
composition of the metals but it's not
necessarily
going to tell you what's what's through
the item
so you know if an item is is plated with
gold
and has has other materials like
tungsten or something on the inside
that may not be picked up by the by the
xre for other items
um so anyway this is the gold screen box
let's switch it on and give you guys a
demo see how
see how this works
the gold's green box is utilizing
electrical conductance of metals for
for its measurement principle given
every metal exhibits a characteristics
conductance value which enables the
identification of
falsifications so that's basically
talking about
um you know we what's what's inside the
coin or the bar and what's going to tell
us quickly and accurately what is
what is inside so we'll show you how to
use this we've got the
lcd screen on the left here
we'll run the calibration first off
before we begin any testing
and that involves placing a copper coin
onto the testing area
so there our patented inductive testing
method uses low
frequency electromagnetic alternating
fields
so it's very very uh clever little
device
we use it all the time tells you
instantly
uh whether a coin is uh genuine not or
not
and composed of the correct material the
quick alloy
of of any item that you that you
want to be testing um so after this
calibration is done we've got a range of
different
coins here that will go through and show
you how we how we use this device to
quickly and accurately
test them which is just really
interesting
so this calibration is almost done
okay so that calibration is complete
so pushing the pushing the button on the
slide brings up the
brings up the menu here for us
so here we've got the preset values of
different different purities of gold
silver and of course we can test
platinum and palladium as well
so pure gold and different
combinations here which are discussed
shortly but if we want to test the pure
gold
item we've turned that onto the pure
gold
we have one of the newest coins from the
perthman here the gold ox
this coin is in a plastic capsule
so previously xrf may or may not have
required you to take that out of the
capsule or not
we place that on the testing device and
we'll see that sitting
sitting in the upper end of the green
band
and we have the desired conductivity
number here and the actual one that it's
showing so there will be little
variations depending on the exact
surface of the coin any scratches
shapes deformations that type of thing
will will produce a slightly different
result
so i've been able to tell instantly yes
that coin
is good um a couple of other items here
perth mint one ounce gold kangaroo again
in the capsule
and straight away we can tell that
sitting well within the correct range
that it should be
gold maple
which is reading all good as well
moving on to some items here pam
bars and blister packs um
look good package is okay
so let's test it and see what happens
so straight away we're seeing that this
is not even close to
what the desired reading should be
change the bar over the other side see
if that's changing the reading
nope we're still well off so clearly
that's a
bar copper filled
fake and here we have a genuine
pamp bar which we'll we'll test
and again straight away that's showing
you that is pure gold
sitting well within the testing range
that it should be some other perth mint
uh products here this is the
one ounce gold minted bar comes in the
certified card
tamper proof pack as well from perth
mint
again that's uh instantly telling us
that is that is a good product
um something we do as well which the
device is
not really set up for but we find that
we find it useful
can test the 10 ounce goldmanted bar as
well
and just for fun let's see what it's
going to do on a kilo
yep so that's reading good as well
for other coins uh krugrains and the
like
it's calibrated for that as well
so i have the gold krugerrand coin here
22 carat
loaded with copper
and that's showing us reading perfectly
within the range here
so gold's green box excellent method of
testing
alongside other advisable
ways as well to know what you're
purchasing know what you're trading
dimensions size would be something you
could compare as well
weight of course against what the coin
should be
so it's potentially quite easy to make a
product that's going to fill one of the
tests but very difficult to make
something that's kind of
going to fill two or more which is where
we find this device
absolutely fantastic ourselves giving us
very very quick
and accurate readings of of gold
products that we need to test
so it's an excellent device highly
recommend getting one of these
my gold's here to help we've been
appointed
exclusive distributors for asia pacific
so any questions
please comment let us know we'd be happy
to help
