hi everyone rich mygold here i'm very pleased to give you all a quick demo of this
really great little device called the "gold screen box" which we use every
day for quickly and accurately determining if precious metals items are genuine or not
i saw this device in berlin earlier this year invented by some extremely talented scientists and
engineers over there and they've created this device and patented it patented it uses the
electrical conductance method for measuring given every metal is exhibiting a characteristic
conductance value so we use this to identify items very very quickly and accurately
as part of our toolkit of other ways for testing and analyzing precious metals so
i've just switched the device on here we have the lcd screen to the left testing area to the right
and let's just jump right into it here it has a bunch of preset modes which is super
handy that's just going to dial up whatever purity of metal you're expecting it to be
you know from pure gold to the different alloys and compositions so krugerrands american eagles
sovereigns and all kinds of other other european coins
in this demo let's just jump straight into pure silver so i've switched that mode
to the conductance value for pure silver should be so that's a desired reading there that we're
looking for if we take one of our products here canadian silver maple put that on the testing
area of the device here we see that's reading immediately well within the correct range
here so we know that we know that coin is not filled with any other material
it's great for being able to test items without taking them out of their
capsules or blister packs whereas xrf or other methods may require you to do so
again we're seeing the queen's stag coin is reading uh correctly in the range there
other products um year of the pig coin from perth mint again in a large thick capsule
we don't have to take that out of the capsule we don't have to handle it
potentially damage the coin in any way that's going to show us sell us for reading
even larger coins here let's see how this goes
that's probably too large because it's not actually reaching the surface area
of the testing device small one out silver bars
so we see that sitting a little bit down the end but still in the green range if we move that
around a little bit that'll change because different objects have different uh surfaces and
imperfections on them so that will account for
a lot of the times that that's giving us a different range
so that products okay it's sitting a little bit on the lower end so we might want to do some other
other backup testing methods just to confirm that product is what it should be
again different coins
straight away giving us the right reading not a problem at all
and one thing we do which the device wasn't really intended for
but it is also possible to test the conductance of large items in this case a perth mint one kilo
silver bar
one kilo silver stag all good also
so yeah that's the gold screen box everyone fantastic with the device
very very helpful for quickly and accurately
testing testing precious metal items coins and bars we use it all the time every day it's
absolutely excellent in combination with other testing methods because as we know it be easier to
make a coin or a product that's going to fill one of the tests but very very difficult to
make a device that's going to fill two or more testing testing methods so yeah my gold
