Residual chlorine sensors are based mostly on different measuring principles, could be divided into diaphragm polarographic sensor and constant voltage sensor.
Used for steady monitoring of residual chlorine.
เพรสเชอร์เกจ , cathode, anode, electrolyte and cathode coated with a layer of gas permeable skinny movie composition. The remaining chlorine within the tested 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 on the cathode, and these chemical reactions occur in the residual chlorine in the measured answer chlorine is proportional to the current.
fixed voltage sensor, composed of two platinum electrodes and a reference electrode to form a microbattery measurement system. During measurement, a stable electrical potential is maintained on the measuring end of the electrode, and completely different elements are produced under this electrical potential generate totally different, properly linear present intensities.
polarographic sensor is characterised by:
Sensitive reaction, excessive accuracy, good stability
Simple operation and small maintenance
Suitable for all kinds of media, movie is not easy to break, air pollution resistance
constant voltage type sensor is characterised by:
With steady zero efficiency, to make sure accurate and reliable measurement
Simple construction, easy to clean
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 portable or laboratory setting
Make alignment
Matters needing attention:
PH should be controlled at 5-8pH
The circulate must be controlled at 60-80L/H
The strain is within 4bar

Doing this is among the best approaches to come to suitable decisions when considering these subjects as #keyword#. It in no way hurts to collect details and discover as many handy strategies as possible, so you might desire to visit #links# and observe exactly what they should state.
Residual chlorine sensors are primarily based on totally different measuring ideas, 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 gasoline permeable skinny movie composition. The remaining chlorine in the tested resolution diffuses to the cathode by way of the diaphragm, and the cathode and anode are applicable the polarization voltage can reduce the residual chlorine at the cathode, and these chemical reactions happen in the residual chlorine in the measured solution 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 secure electrical potential is maintained on the measuring finish of the electrode, and totally different parts are produced underneath this electrical potential generate completely different, well linear present intensities.
polarographic sensor is characterized by:
Sensitive response, excessive accuracy, good stability
Simple operation and small maintenance
Suitable for all kinds of media, movie just isn’t straightforward to damage, air pollution resistance
fixed voltage sort sensor is characterized by:
With stable zero performance, to make sure accurate and reliable measurement
Simple construction, straightforward to scrub
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 conveyable or laboratory setting
Make alignment
Matters needing attention:
PH ought to be controlled at 5-8pH
The move must be managed at 60-80L/H
The stress is inside 4bar
