Two chlorine sensor measuring precept

Residual chlorine sensors are based mostly on completely 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 movie composition. The remaining chlorine within the examined answer diffuses to the cathode by way of the diaphragm, and the cathode and anode are appropriate the polarization voltage can reduce the residual chlorine at the cathode, and these chemical reactions occur within the residual chlorine in the measured resolution 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 secure electrical potential is maintained at the measuring end of the electrode, and totally different parts are produced under this electrical potential generate different, properly linear current intensities.
polarographic sensor is characterized by:
Sensitive reaction, excessive accuracy, good stability

Simple operation and small upkeep

Suitable for all types of media, movie isn’t simple to wreck, air pollution resistance

constant voltage type sensor is characterized by:
With stable zero performance, to make sure correct and reliable measurement

Simple structure, straightforward to clean

It is suitable 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 transportable or laboratory setting

Make alignment

Matters needing consideration:
PH ought to be managed at 5-8pH

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

The stress is within 4bar

Residual chlorine sensors are primarily based on completely different measuring ideas, could 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 thin movie composition. เกจวัดแรงดันแบบแห้ง remaining chlorine in the examined solution diffuses to the cathode through the diaphragm, and the cathode and anode are appropriate the polarization voltage can cut back the residual chlorine at the cathode, and these chemical reactions happen in the residual chlorine within the measured resolution 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 on the measuring end of the electrode, and totally different parts are produced under this electrical potential generate totally different, nicely linear present intensities.
