Measuring Type: Precious metal.such as gold,Karat gold,platinum,silver. Mixed metal or other alloy metal. Jewelry materials.such as ring,necklace,bracelet,watchband,belt fastener,gold ingot,gold bar,statue,coin.,etc. Notes: Please check the samples to be tested firstly when do testing: (1).products of which inside is hollow if the hollow is closed.water or other liquids can't get access into,the samples can't be tested if the hollow is opened,water or other liquids can get access into,the samples can be tested (2).products set with precious stones------can't be tested (3).products of which the density is very close to precious metal------can't be tested Features: Distinguish whether the gold,karat gold,platinum,silver,other precious metal is the genuine or not. Test the purity of gold,karat gold,platinum,silver to confirm if the marked content is correct or not. No need to cut samples;also it can be measured immediately. Can shift to measure Karat and purity percentage of gold-silver -copper,gold-copper,gold-silver respectively. Function of density measuring and normal gram scale. Either water or alcohol would be as medium. Function of setting actual water temperature.

Power supply:AC 100V-240V;50HZ/60HZ(Europe standard) Weight/packing size:4.5kg/length 42.5cm X width 17.5cm X height 32.5cm Measurement Resolution and Range: AU-300K weighting resolution:0.005g,minimum weight:4g,density resolution:0.001g/cm3 AU-600K weighting resolution:0.005g,minimum weight:4g,density resolution:0.001g/cm3 AU-120K,200K weighting resolution:0.001g,minimum weight:2g,density resolution:0.001g/cm3 900K,1200K,2000K,3000K weighting resolution:0.01g;minimum weight:5g;density resolution:0.01g/cm3 K value range:9k,10k,11k,12k,13k,14k,15k,16k,17k,18k,19k,20k,21k,22k,23k,24k and % percentage content. Platinum content range:PT600,PT650,PT700,PT750,PT800,PT850,PT900,PT950,PT1000 and % percentage content. Silver content range:S600,S650,S700,S750,S800,S850,S900,S950,S1000 and % percentage content. The proportion of copper-silver for gold-silver-copper can be shifted cyclically with 9/1,8/2,7/3,6/4,5/5,4/6,3/7,2/8,1/9.the default setting is 7/3. Understanding Karats Since gold is a soft metal, it's often combined with other harder metals when it's used in jewelry to provide durability. In general,gold is mixed with silver and copper(Except 24K pure gold).Gold jewelry is measured in 24 parts, called karats (K), to indicate how much of the piece is pure gold. So, if gold is 24K, all 24 parts of the jewelry are gold. Jewelry marked 22K is 22 parts gold, two parts harder metals.which means,the jewelery including 22/24(91.67%) gold,the remaining 2/24(8.3%) belongs to copper-silver mixure,or copper,or silver.Thus, the lower the number, the less gold. As such, 24K gold is the softest, while 10K is significantly the harder.Our machine can test the K value,density,purity percentage for mixure gold-copper-silver,gold-copper,and gold-silver.for jewellery manufacturer,the ratio of gold-silver-copper can be set freely to get the exact K value,density,purity percentage. Identifying Fake Gold Jewelry by a Few Simple Tricks: Check for Discoloration Check for discoloration on the piece of jewelry in places where there would be a lot of friction, such as the inside of a ring band. If it seems to be discolored or chipped in any area, the jewelry is not real gold, and instead may be gold plated or imitation gold. Also, real gold has an even color throughout, but gold-plated items will have poor or uneven tone. Another way to check for discoloration is to wear the jewelry for a full day. If there is discoloration on the skin, the gold is likely fake. Magnet Test The magnet test is an easy way to ensure that gold is genuine. Pure gold is not a magnetic metal, so it will not be attracted by a magnet. Use a magnet that is stronger than a refrigerator magnet and hold it up to the gold item. If the piece pulls toward the magnet, the item may not be real gold. However, this test is not fail safe. Gold jewelry that's more than 20 percent alloy will be slightly attracted to the magnet. In addition, some non-magnetic metals are used in counterfeit gold, so do not let this be the only test to check a supposed piece of jewelry.
