合肥钢铁公司第一炼钢厂试制安装了一台化学元素报数仪,由化学元素管和数字管组成。化验室通过该仪器,以数字显示的方法,向炉前报告分析结果,并以两台小型晶体管对话机传话,便于双方联系。该仪器克服了电子管扩大机的缺点,自1971年4月使用以来,效果良好。由于数字管较小(SZ-8型),当距离较远时,数字不易看清,现在采用氖气灯泡代替元素管。(摘自冶金科技动态1973年第17期)
Hefei Iron and Steel Company’s first trial installation of a steel mill chemical elements reported by the instrument, the chemical elements of the tube and digital tube. Laboratory through the instrument, the method of digital display to the furnace front of the analysis results, and two small transistor telephone conversation, to facilitate contact between the two sides. The instrument to overcome the shortcomings of the tube amplifier, since April 1971 to use, the effect is good. As the digital tube is small (SZ-8 type), when the distance is far, the figure is not easy to see, now use neon bulbs instead of element tubes.
