Residual chlorine sensors are primarily based on totally different measuring rules, can be divided into diaphragm polarographic sensor and fixed voltage sensor.
Used for steady monitoring of residual chlorine.
diaphragm polarographic sensor, cathode, anode, electrolyte and cathode covered with a layer of gas permeable thin film composition. The remaining chlorine in the examined resolution diffuses to the cathode through the diaphragm, and the cathode and anode are applicable the polarization voltage can cut back the residual chlorine at the cathode, and these chemical reactions occur in the residual chlorine within the measured solution chlorine is proportional to the present.
fixed voltage sensor, composed of two platinum electrodes and a reference electrode to form a microbattery measurement system. During measurement, a steady electrical potential is maintained at the measuring finish of the electrode, and completely different elements are produced underneath this electrical potential generate different, nicely linear current intensities.
polarographic sensor is characterized by:
Sensitive reaction, excessive accuracy, good stability
Simple operation and small maintenance
Suitable for every kind of media, movie is not straightforward to wreck, pollution resistance
fixed voltage type sensor is characterised by:
With steady zero performance, to ensure correct and dependable measurement
Simple construction, easy to clean
It is suitable for measuring residual chlorine, chlorine dioxide and ozone in water
Correction:
Zero point correction
Zero correction with chlorine-free water
Slope correction
Actual measurements are made in a transportable or laboratory setting
Make alignment
Matters needing consideration:
PH should be managed at 5-8pH
The flow should be controlled at 60-80L/H
The strain is inside 4bar

Residual chlorine sensors are based on totally different measuring principles, can be divided into diaphragm polarographic sensor and fixed voltage sensor.
Used for steady monitoring of residual chlorine.
diaphragm polarographic sensor, cathode, anode, electrolyte and cathode coated with a layer of gas permeable thin movie composition. The remaining chlorine within the examined solution diffuses to the cathode via the diaphragm, and the cathode and anode are acceptable the polarization voltage can reduce the residual chlorine on the cathode, and these chemical reactions happen in the residual chlorine within the measured resolution chlorine is proportional to the current.
