Overview

RY-830 is a brand new ppb level dissolved oxygen analyzer designed specifically for measuring ppb level dissolved oxygen in boiler feedwater and condensate water based on new polarographic analysis technology. A series of analytical techniques have been adopted to ensure stability and accuracy at (ultra) low concentrations, with significant improvements in measurement performance and usage environment. The features include Chinese display, Chinese menu operation, and powerful functionality. It can be widely used for continuous monitoring of dissolved oxygen values in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.
