YLG-2058 Industrial Online Residual Chlorine Analyzer
YLG-2058 Industrial Online Residual Chlorine Analyzer is a bran-new residual chlorine analyzer in our company; It is a high-intelligence on-line monitor, It is made up of three parts: a secondary instrument and a sensor, a organic glass flow cell. It can measure residual chlorine, pH and temperature simultaneously. It can be widely used for continuous monitoring of residual chlorine and pH value of various water quality in power, water plants, hospitals and other industries.
English Display, English Menu operation: Easy operation, English prompts during the whole operational |
procedure ,convenient and quick. |
Intelligent: It adopts high-precision AD conversion and single chip microcomputer processing technologies and |
can be used for the measurement of the PH values and temperature, automatic temperature compensation and |
self-checking etc function. |

YLG-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.
