SW-XRA Series Gold Analyzer
Why Use X-Ray Gold Analyzer?
Now gold price is very high, and gold analysis method is becoming more important. For example, gold price is USD1500 per ounce; if analysis method tolerance is more than 1%, then customers wills lose as follows:1 ounce loses USD15, 1Kg loses USD15*(1000/31.1)=USD482If a gold buyer buys 5Kg gold every day, then he will lose about USD2410.So for jewelers and gold buyers, choosing a correct gold analysis method and equipment is very important.
