The HK-portable oxidant gas direct-reading Colorimeter suitable for the on-site measurement of medium and high concentration oxidant gas was developed, and compared with the measurement results of oxidative gas by the five-step stone method and the traditional spectrophotometric method, the results showed that the three methods were more accurate The results are consistent, and HK-portable: portable = oxidant gas direct-reading Colorimeter can accurately and quickly measure the results on site.
In this paper, a portable photoelectric direct-reading Colorimeter suitable for the on-site determination of medium and high concentrations of chlorine dioxide is developed, and it is compared with the five-step iodometric method and the traditional spectrophotometric method for the determination of chlorine dioxide produced by activation and generation and diluted in a certain proportion. The comparison shows that the results of the HK-portable chlorine dioxide direct-reading Colorimeter are consistent with the spectrophotometric method and the five-step iodometric method, and the instrument is easy to operate, small in size, light in weight, good in stability and strong in real-time It can accurately and quickly measure the concentration of chlorine dioxide used on site.
