Application:
It used for Gold Jewelry industry , bank , Pawn industry , Gold and
Precious Metal research lab .
Principle:
According to the buoyancy method of Archimedean principle , can
show gold karat density and purity% rapidly and accurately .
Characters:
1. Hot sales gold density testing machine especially for Gold need
Only two weighing steps , the purity% of precious metals and gold
karat can be showes rapidly and accurately .
2. No stains and scratches left on gold after testing , it doesn't
need to use the sulfuric acid solution to test the standard samples
.
3. Hot sales gold density testing machine especially for Gold With
the special software design , it can directly and circularly show
the gold karat (including gold-copper-silver , gold-copper , gold
-silver), gold purity% (including including gold-copper-silver ,
gold-copper , gold -silver )
4. Hot sales gold density testing machine especially for Gold With
the function of HI and LO limit , the wide karat range from 9K to
24K and the data of HI and LO can be set freely .
5.With the mixture proportion function , it can test other pricious
metals , such as : platinum , silver , palladium , copper ,
rhodium.....and so on .
6. Hot sales gold density testing machine especially for Gold By
adopting the design of big tank , it can decrease the inaccuracy
caused by supporting wire's buoyancy
7. Hot sales gold density testing machine especially for Gold Can't
test the samples inlaid precious stones and hollow samples . It can
be used as general balance .
