CL-2058-01 Polarographic residual chlorine sensor electrode
Typical applications
Suitable for drinking water, industrial process water disinfection technology residual chlorine concentration online monitoring, can also be used for swimming pools and other places chlorine concentration measurement.
Measuring principle
Chlorine is a diaphragm-type polarographic electrode (clark) sensor, integrated by the cathode, anode, electrolyte and cathode covered with a layer of gas permeable film. In the test solution, residual chlorine diffuse through the membrane to the cathode, a suitable polarization voltage between the cathode and the anode can deoxidize residual chlorine at the cathode, such chemical reaction with chlorine in solution is proportional to the current measurement.
Features
Responsive, high accuracy, good stability.
Simple operation, easy maintenance.
Applicable to a variety of media, durable film , pollution resistant.
