Residual chlorine sensors are based mostly on totally different measuring principles, can be divided into diaphragm polarographic sensor and fixed voltage sensor.
Used for continuous monitoring of residual chlorine.
diaphragm polarographic sensor, cathode, anode, electrolyte and cathode coated with a layer of gas permeable thin film composition. The remaining chlorine in the examined resolution diffuses to the cathode through the diaphragm, and the cathode and anode are acceptable the polarization voltage can reduce the residual chlorine at the cathode, and these chemical reactions happen in the residual chlorine in the measured answer chlorine is proportional to the current.
constant 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 on the measuring end of the electrode, and totally different parts are produced under this electrical potential generate completely different, nicely linear current intensities.
polarographic sensor is characterised by:
Sensitive reaction, high accuracy, good stability
Simple operation and small upkeep
Suitable for all kinds of media, movie isn’t simple to break, air pollution resistance
constant voltage type sensor is characterised by:
With steady zero performance, to make sure correct and dependable measurement
Simple structure, easy 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 portable or laboratory setting
Make alignment
Matters needing consideration:
PH should be managed at 5-8pH
The move should be managed at 60-80L/H
The stress is within 4bar

There are countless approaches to handle #keyword# many of them are challenging. It will almost certainly require you a while before you discover the route. There are numerous varying views amongst individuals as to what exactly functions, and what is effective for one particular person might have hit a brick wall for another. The simple truth is, this is to be expected. It’s up to you to take a look at various methods and make your own alternative as to what’s most effective for you. That’s the way things move when you’re coping with #keyword#. Flexibility is the finest technique as you move ahead to the future stage. If you want to have a look at some additional thoughts along with common-sense hints, you will discover all these awaiting you at #links#.
Residual chlorine sensors are primarily based on totally different measuring ideas, could be divided into diaphragm polarographic sensor and fixed voltage sensor.
Used for steady monitoring of residual chlorine.
pressure gauge nuova fima ราคา , cathode, anode, electrolyte and cathode covered with a layer of fuel permeable thin movie composition. The remaining chlorine in the examined solution diffuses to the cathode through 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 happen within the residual chlorine in the measured solution chlorine is proportional to the current.
fixed voltage sensor, composed of two platinum electrodes and a reference electrode to kind a microbattery measurement system. During measurement, a stable electrical potential is maintained at the measuring finish of the electrode, and totally different components are produced underneath this electrical potential generate totally different, well linear present intensities.
polarographic sensor is characterised by:
Sensitive response, high accuracy, good stability
Simple operation and small upkeep
Suitable for every kind of media, movie just isn’t simple to wreck, air pollution resistance
fixed voltage sort sensor is characterised by:
With steady zero efficiency, to ensure accurate and dependable measurement
Simple structure, simple to wash
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 must be controlled at 5-8pH
The circulate ought to be controlled at 60-80L/H
The stress is within 4bar
