Density precision


●Only two weighing steps, karat, density and purity of gold can be showed rapidly and accurately. 

●With the mixture proportion function, it can be used for testing density and purity of platinum, silver and other metals.
●With the special software design, it can directly and circularly show the gold karat (including  gold-copper-silver, gold-silver, gold-
copper), gold purity%(including gold-copper-silver, gold-silver, gold-copper)
●With the function of HI and LO limit, the wide karat range from 9K to 24K and the HI and LO value can be set freely.
●No stains and scratches left on gold after testing, it doesn’t need to use the sulfuric acid solution to test the standard samples.
●Pure water or distilled water can be used as testing medium, it is low cost and easily got.
●By adopting the design of big tank, it can decrease the inaccuracy caused by supporting wire’s buoyancy.
●Can’t test hollow samples and the samples with precious stones; it can be used as general balance.
