Detection principle of nitrogen oxide detector
Detection principle of nitrogen oxide detector
The key component of the nitrogen oxide detector is the gas sensor. Gas sensors can be divided into three categories in principle:
A) Gas sensors using physical and chemical properties: such as semiconductor type (surface control type, volume control type, surface potential type), catalytic combustion type, solid thermal conductivity type, etc.

Introduction of oxygen concentration detector
The oxygen concentration detector can play a continuous online detection of concentration and on-site sound and light alarm, and play an early warning role in the operation safety of dangerous sites. The oxygen concentration detector adopts imported electrochemical sensor and microcontroller technology, which has the advantages of stable signal, high precision and good repeatability. The explosion-proof wiring mode is suitable for various dangerous places. The instrument is compatible with various control alarms, PLC, DCS and other control systems, and can simultaneously realize on-site alarm and remote monitoring and alarm functions. The oxygen detection and alarm integrated machine is suitable for continuous on-line detection of oxygen concentration in various industrial environments and special environments and on-site sound and light alarm, which plays an early warning role in the operation safety of dangerous sites.

Ozone Tester Circuit Principle
The ozone tester uses the principle of ultraviolet absorption method, uses a stable ultraviolet light source to generate ultraviolet light, and uses a light wave filter to filter out other wavelengths of ultraviolet light, only allowing the wavelength of 253.7nm to pass. After the sample photoelectric sensor, and then through the ozone absorption cell, to reach the sampling photoelectric sensor. By comparing the electrical signals of the sample photoelectric sensor and the sampling photoelectric sensor, and then through the calculation of the mathematical model, the ozone concentration can be obtained.

Precautions in the use of oxygen detector
In the analysis of oxygen content, especially in the treatment of rheumatoid arthritis, the oxygen content in the air is as high as 21% O2, so if it is not handled properly, it is very easy to cause pollution and interference to the sample, and the analysis result data is incorrect. The main reason is the improper operation of the oxygen detector. The following only talk about a few factors affecting the determination:
