Two chlorine sensor measuring principle

Residual chlorine sensors are based mostly on different measuring principles, could be divided into diaphragm polarographic sensor and constant voltage sensor.
Used for continuous monitoring of residual chlorine.
ขนาดpressuregauge , cathode, anode, electrolyte and cathode coated with a layer of gas permeable skinny movie composition. The remaining chlorine in the examined solution diffuses to the cathode via the diaphragm, and the cathode and anode are appropriate the polarization voltage can cut back the residual chlorine on the cathode, and these chemical reactions happen within the residual chlorine within the measured resolution chlorine is proportional to the current.
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 on the measuring finish of the electrode, and totally different components are produced beneath this electrical potential generate different, well linear present intensities.
polarographic sensor is characterised by:
Sensitive reaction, excessive accuracy, good stability

Simple operation and small upkeep

Suitable for all kinds of media, film isn’t straightforward to damage, pollution resistance

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

Simple structure, simple 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 transportable or laboratory setting

Make alignment

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

The flow must be managed at 60-80L/H

The strain is within 4bar

Residual chlorine sensors are primarily based on different measuring principles, may be divided into diaphragm polarographic sensor and constant voltage sensor.
Used for continuous monitoring of residual chlorine.
diaphragm polarographic sensor, cathode, anode, electrolyte and cathode covered with a layer of fuel permeable thin movie composition. The remaining chlorine in the tested resolution diffuses to the cathode through the diaphragm, and the cathode and anode are acceptable the polarization voltage can cut back the residual chlorine at the cathode, and these chemical reactions occur 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 stable electrical potential is maintained at the measuring end of the electrode, and different components are produced under this electrical potential generate totally different, properly linear current intensities.
polarographic sensor is characterized by:
Sensitive response, excessive accuracy, good stability

Simple operation and small upkeep

Suitable for every kind of media, movie is not easy to break, pollution resistance

constant voltage kind sensor is characterised by:
With steady zero performance, to make sure correct and reliable measurement

Simple construction, simple 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 consideration:
PH must be controlled at 5-8pH

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

The strain is inside 4bar
