The device is capable of determining the elemental composition of all gold alloys, platinum group metals and silver alloys. Furthermore, the instrument is well suited for determining gold coating on the other materials. The measuring process is fully non-destructive and leave the chemical and physical properties of sample intact. KM2918 is specially designed to meet all requirements of the analysis systems used in jewelry retail store and jewelry manufactory.
