Description

JB750 Optical Emission Spectrometer is the best assistant for rapid quantitative analysis of metallurgical furnace and metallic quality monitoring. Its accuracy and stability meet laboratory requirements and can make measurements for dozens of matrix based on elements such as Fe,Al,Cu,Ni,Co,Ti,Mg,Zn,Sn,Pb, etc. It is widely used in steel, metallurgy, foundry and machinery for IQC, QC and OQC.
JB-750 is a design of zero fault operation, which requires little maintenance and offering high reliability and convenience.
