Scope of application of portable dissolved oxygen analyzer

Portable Dissolved Oxygen Analyzer

Portable Dissolved Oxygen Analyzer is a high-performance portable measuring instrument. It is used to measure the concentration of oxygen content in aqueous solution. With a measurement accuracy of micrograms, high measurement accuracy, easy operation. And effectively avoids oxygen leakage, especially suitable for ultra-pure.  The detection of low-concentration dissolved oxygen in water is widely used in petrochemical, electric power, beverage, pharmaceutical. And semiconductor industries.

water quality sensor

Instrument Features

1. The polarographic trace dissolved oxygen detection electrode is used, which is suitable for the detection of low concentration oxygen content. And the measurement accuracy is microgram level.

2. Solid airtight design. The protection level reaches IP65, which can meet the use of complex sites

3. Wide temperature, high brightness 12864 OLED dot matrix liquid crystal display, large viewing angle, suitable for use in dark and low temperature

The industry related to teaching instruments involves many fields. With the development of the country, the advancement of science and technology. The expansion of the scale of education and teaching, the demand for scientific. And educational instruments is also showing a trend of rapid growth. And the market demand is huge. Here we have to focus on It introduces the application. And classification of teaching instruments related to water quality testing.

Monitoring principle

Water quality testing or analysis and testing of liquid samples occupy a large part of laboratory teaching. Such as laboratory water quality analysis and testing. Biological fermentation process testing. Environmental governance testing, etc. In these experiments, many indicators need to be detected, such as pH. ORP. DO, residual chlorine. Ammonia nitrogen content, etc.. And various water quality detection sensors will be used in the detection of these indicators.

The dissolved oxygen sensor mainly determines the dissolved oxygen content in the water by measuring . And the oxygen dissolved in the water. Through the gas permeable membrane of the sensor to reach the electrode surface. And then a reduction reaction occurs to generate an electric current. In related experiments such as fermentation. And culture process monitoring. Environmental governance process monitoring. And aquatic animal habit research. The dissolved oxygen content in the aqueous solution will be measured.
