一、前言近年来随着电子技术的飞速发展,滴定分析仪有了较大的进展,国外已研制成功了用计算机控制和直接数字自动滴定仪,对滴定剂的传递、计量、滴定控制系统、滴定终点测量技术和滴定曲线的记录方式等,也都有创新和改进,使滴定分析仪在数字化、自动化,测量速度,测量精度,适应范围等方面均有发展。国内有许多单位对钢铁碳硫的自动滴定分析做了大量的工作,取得了满意的效果。 I. Introduction In recent years, with the rapid development of electronic technology, titration analyzer has made great progress, foreign countries have successfully developed a computer-controlled and direct digital automatic titrator, titrant delivery, measurement, titration control system, Titration endpoint measurement techniques and titration curve recording methods, but also have innovation and improvement, the titration analyzer in the digital, automation, measurement speed, measurement accuracy, the scope of adaptation and so on have developed. Many domestic units do a lot of work on the automatic titration analysis of carbon and sulfur in steel and have achieved satisfactory results.
