Product description:
Shanghai Shuju Precious Metal Detector is a fast analytical instrument for measuring the purity of gold, non-destructive measurement of samples, can quickly display purity, K value, density value. It has the characteristics of accurate measurement, simple operation, fast, reliable performance, and economical benefits. Applicable to: jewelry industry, banks, pawn shops, gold and precious metals research laboratories. It complies with the national GB/T1423 precious metal purity determination method specification.
Product features:
◇ Large screen LCD display
◇ With RS-232C computer interface, it can easily print.
◇ Built-in battery, more suitable for on-site testing
◇ It can quickly and accurately determine the purity% of precious metals and the K number of gold: only two weighing steps are required.
◇ No traces or pollution will be left after the measurement, no need to use sulfuric acid solution or test standard samples.
◇ With upper and lower limit functions, a wide range of K numbers from 1K to 24K can freely set HI and LO data.
◇ With mixing ratio function, it can test other precious metals. Such as: platinum, silver, palladium, copper, rhodium… etc.
◇ It can also be easily judged for Brazilian fired gold with a coating thickness of >30μm or more.
◇ Special software design, can cycle display gold K number (including gold copper silver, gold silver, gold copper), gold purity% (including gold copper silver, gold silver, gold copper)
