Residual chlorine sensors are based on 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 lined with a layer of gasoline permeable skinny film composition. The remaining chlorine within the tested answer 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 in the residual chlorine within the measured answer chlorine is proportional to the present.
fixed voltage sensor, composed of two platinum electrodes and a reference electrode to type a microbattery measurement system. During measurement, a stable electrical potential is maintained at the measuring end of the electrode, and totally different parts are produced underneath this electrical potential generate completely different, well linear current intensities.
polarographic sensor is characterised by:
Sensitive reaction, excessive accuracy, good stability

Simple operation and small upkeep

Suitable for all types of media, movie is not easy to break, pollution resistance

fixed voltage type sensor is characterized by:
With steady zero performance, to ensure accurate and dependable measurement

Simple construction, straightforward 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 portable or laboratory setting

Make alignment

Matters needing consideration:
PH should be controlled at 5-8pH

The flow should be controlled at 60-80L/H

The strain is within 4bar

Residual chlorine sensors are primarily based on totally different measuring principles, can be divided into diaphragm polarographic sensor and constant voltage sensor.
Used for เกจวัดแรงดัน of residual chlorine.
diaphragm polarographic sensor, cathode, anode, electrolyte and cathode covered with a layer of gas permeable skinny film composition. The remaining chlorine in the tested solution 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 happen within the residual chlorine within the measured answer 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 stable electrical potential is maintained on the measuring end of the electrode, and totally different elements are produced under this electrical potential generate completely different, nicely linear current intensities.
polarographic sensor is characterized by:
Sensitive reaction, high accuracy, good stability

Simple operation and small maintenance

Suitable for every kind of media, film is not easy to damage, pollution resistance

fixed voltage kind sensor is characterized by:
With secure zero efficiency, to make sure accurate and dependable measurement

Simple structure, easy to scrub

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 portable or laboratory setting
