Abstract: BM2010A multi-element measuring apparatus as the quantitative analysis apparatus is developed based on requirements of cement enterprise. It is mainly used to detect CaO%, Fe₂O₃%, SiO₂% and Al₂O₃% content in slurry as well as SO₃% content in clinker or cement so as to quickly supply analysis data for slurry mixture ratio and clinker rate value, analyze CaO%, Fe₂O₃%, SiO₂%, Al₂O₃% and SO₃% content in limestone, clay, gypsum, slag and other materials to supply quality data for incoming raw materials, detect CaO% and SO₃% content in cement so as to provide analysis data for mixing quantity of composite materials in cement. In this way, element control improved to rate value control can be realized in production. BM2010A multi-element measuring apparatus can also be used to other occasions whether CaO%, Fe₂O₃%, SiO₂%, Al₂O₃% and SO₃% shall be analyzed, such as  kaolin, refractory, slag powder, etc.

Main feature: 

(1) Free from radioactive source, it is within the management range exempted by environmental protection department; 

(2) Large liquid crystal display and Chinese menu are convenient for operation; 

(3) Automatic audio alarm, keyboard printer in panel and operation in man-machine interactive mode; 

(4) Physical analysis method is adopted to avoid sample contact or damage during analysis process. It is unnecessary to adopt chemical agent; 

(5) Highly integrated instrument to guarantee powerful adaptive capacity to environment and interference-free feature; 

(6) Instrumental analysis system can be used independently or used together with microcomputer material proportioning system by connecting through RS232 or RS485 standard serial port; 

(7) Two elements are analyzed at the same time quickly. We adopt "continuous measurement method of standard sample" so as to obtain the result with high precision in 30s; 

(8) Strong software function and great data storage capability; Software function can be added as required by users to guarantee high cost performance; 

(9) After measurement is completed, "pull-out measurement tray" warning function is prompted within 8s (new functions are unavailable from other manufacturers)
