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.

Features

• 750 mm focal length grating design with palmer type-runge device which has the features of high vacuum, high resolution and high sensitivity etc.
•  Adopt high stability digital sources. You can choose different excitation parameters to analyze different samples which can get the best analysis results.
• The automation is very high which adopts high integration of the acquisition and control system.
• The photomultiplier tubes from Hamamatsu which has the features of low dark current, high signal-to-noise ratio, long service life etc.
•  It can be used for variety of bases such as Fe, Al, Cu, Co, Ni, Pb, Mg, Zn, Sn etc.
•  The temperature of the optical part is stable which ensure the instrument running well and reduce the requirement of the environment.
• The system adopts independent power supply and becomes unit which is easy to use and simple maintenance.
• The computer adopts Windows 7 system and English operation software which is simple to understand.
