For the chemical industry, chemical instruments are very important production equipment. In order to promote the development of chemical industry, it is required that chemical instruments need to realize intelligent automation. The intelligent and automatic chemical instrument can carry out real-time monitoring on various production data. In the actual chemical production process, there are various types of chemical instruments involved. No matter what type of instrument is, it is necessary to realize intelligent automation to improve chemical production efficiency.展开更多
