Description
OverviewÂ
GAOTek Intelligent Residual Chlorine Meter with Platinum Electrodes for Industrial Use is a totally new industrial residual chlorine analyzer, with high intelligence and sensitivity. It can measure residual chlorine and temperature simultaneously. It is widely used in such industries as thermal power plants, running water, pharmaceutical, drinking water, water purification, industrial pure water, swimming pool is infection residual chlorine continuous monitoring. This is an electrode for measuring the constant voltage principal water chlorine, chlorine dioxide, ozone. Constant voltage measurement maintains a stable electric potential at the measurement side of the electrode, different components produce different current intensity at the electric potential when measured. The micro-current measurement system consists of two platinum electrodes and a reference electrode consisting of. Chlorine, chlorine dioxide, ozone will be consumed when water sample flowing through the measuring electrode, therefore, must maintain the water sample continue flow the measuring.Â
