Overview
GR-F-Chlorine residual chlorine water quality online automatic monitoring instrument can remove chlorine (total chlorine, chlorine dioxide), ozone, and temperature transmitters. This transmitter is used for measuring chlorine removal, total chlorine, chlorine dioxide, and chlorine addition control. It is widely used in industries such as tap water, drinking water, purified water, industrial pure water, and swimming pool disinfection. The monitoring method used by this instrument is constant voltage measurement, which continuously and dynamically controls the potential between the measuring electrodes through a secondary instrument, eliminating the influence of the inherent resistance and redox potential of the measured water sample, and forming a good linear relationship between the electrode measurement current signal and the concentration of the measured water sample. It has very stable zero point performance, ensuring accurate and reliable measurement.
