溶液的浓度,往往是决定产品质量的主要指标。过去国内还没有比较理想的检测溶液浓度的仪表。福建漳州自动化仪表厂试制成功了光电浓度变送器,并已鉴定和批量生产,它可以对溶液的浓度进行连续自动测
The concentration of the solution is often the main indicator of product quality. In the past, there is no ideal test solution concentration instrument. Zhangzhou, Fujian Automation Instrumentation plant trial success photoelectric concentration transmitter, and has been identified and mass production, it can be the concentration of the solution for continuous automatic measurement
