Ozone Tester Circuit Principle

The ozone tester adopts the principle of ultraviolet absorption method, uses a stable ultraviolet light source to generate ultraviolet light, uses a light filter to filter out other wavelengths of ultraviolet light, and only allows the wavelength of 253.7nm to pass. After passing through the sample photoelectric sensor, and then through the ozone absorption cell, it reaches the sampling photoelectric sensor. The ozone concentration can be obtained by comparing the electrical signals of the sample photoelectric sensor and the sampling photoelectric sensor, and then through the calculation of the mathematical model.

Industry News Precautions in the use of oxygen detectors

In the analysis of oxygen content, especially in the treatment of rheumatoid arthritis, since the oxygen content in the air is as high as 21% O2, it is very easy to contaminate and interfere with the sample if it is not handled properly, and the analysis result data will be incorrect. The main reason is the improper operation of the oxygen detector. Here are just a few factors that affect the measurement:
