Digital density meter JL-SD

industrial

– Suitable for: 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 accuratel. Functions: ● 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. ● Standard size of water tank: 150 * 100 * 90 mm.
