dissolved oxygen sensor KDS-25B profile:
The dissolved oxygen sensor KDS-25B uses a special acidic electrolyte, the cathode uses inert metal gold, the anode uses metal lead, and oxygen participates in the oxidation-reduction reaction through the fluorine resin membrane in a diffusion manner to form an oxygen lead-acid battery, and then the internal resistance will reduce the oxidation The current generated by the reaction is converted into voltage output. The generated current is proportional to the concentration of dissolved oxygen, strictly speaking, it is proportional to the oxygen partial pressure (the higher the dissolved oxygen content, the more oxygen molecules through the fluorine resin membrane to participate in the reaction). The dissolved oxygen sensor is KDS-25B one of the ideal sensors for environmental monitoring and water quality detection.
Dissolved oxygen sensor KDS-25B basic parameters:
① Range: 0-80mg/L;
② Atmospheric pressure: 81-203kPa;
③ Temperature/humidity range: 5-35 ℃,10-90% RH;
The thermal constant of the thermistor: about 10 minutes;
⑤ Response time: T90 is about 20S,T100 is within 60S;
The initial output in the air under standard conditions: 8-15mV;
Dissolved oxygen sensor KDS-25B main features:
1) Not affected by CO2 and other acidic gases;
2) Long life (life expectancy of 3 years);
3) High accuracy (± 5% full scale);
4) Built-in thermistor for temperature compensation;
5) no preheating, no external power supply;
Dissolved oxygen sensor KDS-25B typical applications:
1) the aquaculture industry;
2) On-line environmental monitoring;
3) Water source monitoring and sewage treatment industry;
4) Investigation of water pollution in education and scientific research fields;

Abstract: This paper summarizes various detection methods and principles of dissolved oxygen in water bodies, such as iodine method, current measurement method (Clark dissolved oxygen electrode), conductivity measurement method, fluorescence quenching method, etc., compares the advantages and disadvantages of various methods, and makes a preliminary discussion on the application prospect of fluorescence quenching method... The Importance of Dissolved Oxygen (DO) and DO Measurement Dissolved oxygen is an indispensable condition for the survival of aquatic organisms. A source of dissolved oxygen is when the dissolved oxygen in the water is not saturated... In view of the fact that the optical fiber sensor based on the fluorescence quenching method measuring instrument has high measurement accuracy and strong anti-interference ability... Optical detection technology for dissolved oxygen in beer brewing industryConventional DO detection in the beverage industry employs an electrochemical analysis system using a Clark type or similar sensor. The electrochemical oxygen detection principle is to reflect the amount of dissolved oxygen by measuring the current generated by the redox reaction... Dissolved oxygen measurement Application introduction Continuous measurement of dissolved oxygen in the sewage treatment aeration tank When measuring dissolved oxygen in the aeration tank, the sensor is easily contaminated, so it needs to be cleaned frequently. yookogawa motor high quality DO402 dissolved oxygen converter system high efficiency... Principle of dissolved oxygen analyzer_sensor Some do not even do the mounting bracket, directly put the sensor into the water, so that between the sensor and the cable will form a larger tension, the sensor is more likely to be damaged. dissolved oxygen probe weekly application of water gently cleaning, found that the membrane head damage should be in a timely manner... |
