Funktionen:
● 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-
Kupfer), 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.
● Standard size of water tank: 150 * 100 * 90 mm.
