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

The strain is inside 4bar
