Residual chlorine sensors are primarily based on different measuring principles, may 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 fuel permeable skinny film composition. The remaining chlorine in the tested solution diffuses to the cathode by way of the diaphragm, and the cathode and anode are applicable the polarization voltage can scale back the residual chlorine on the cathode, and these chemical reactions occur within the residual chlorine in the measured solution chlorine is proportional to the present.
fixed pressure gauge 10 bar , composed of two platinum electrodes and a reference electrode to kind a microbattery measurement system. During measurement, a steady electrical potential is maintained on the measuring finish of the electrode, and different elements are produced beneath this electrical potential generate different, properly linear current intensities.
polarographic sensor is characterized by:
Sensitive response, high accuracy, good stability
Simple operation and small maintenance
Suitable for all kinds of media, movie is not straightforward to wreck, air pollution resistance
fixed voltage kind sensor is characterized by:
With secure zero performance, to ensure accurate and dependable measurement
Simple construction, easy to clean
It is appropriate for measuring residual chlorine, chlorine dioxide and ozone in water
Correction:
Zero level correction
Zero correction with chlorine-free water
Slope correction
Actual measurements are made in a conveyable or laboratory setting
Make alignment
Matters needing attention:
PH should be managed at 5-8pH
The move ought to be controlled at 60-80L/H
The pressure is inside 4bar

Residual chlorine sensors are primarily based on different measuring rules, could be divided into diaphragm polarographic sensor and constant voltage sensor.
Used for steady monitoring of residual chlorine.
diaphragm polarographic sensor, cathode, anode, electrolyte and cathode coated with a layer of gasoline permeable thin movie composition. The remaining chlorine in the tested resolution diffuses to the cathode via the diaphragm, and the cathode and anode are acceptable the polarization voltage can scale back the residual chlorine at the cathode, and these chemical reactions occur within the residual chlorine within the measured solution chlorine is proportional to the present.
constant voltage sensor, composed of two platinum electrodes and a reference electrode to type a microbattery measurement system. During measurement, a steady electrical potential is maintained at the measuring end of the electrode, and different elements are produced underneath this electrical potential generate completely different, nicely linear present intensities.
polarographic sensor is characterised by:
Sensitive response, high accuracy, good stability
Simple operation and small upkeep
Suitable for all types of media, movie isn’t simple to damage, pollution resistance
fixed voltage type sensor is characterized by:
With secure zero performance, to ensure accurate and dependable measurement
Simple structure, straightforward to scrub
It is appropriate 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 ought to be controlled at 5-8pH
The move should be controlled at 60-80L/H
