How to meet Ozone Concentration in Air?

Ozone is an important environmental factors that can not only protect the earth from ultraviolet damage, but also kill bacteria and viruses, and improve air quality. However, excessive ozone or too little ozone can cause harm to humans and ecosystems, so we need to monitor the concentration of ozone in time. So, how to meet Ozone Concentration in Air? Here are several commonly used ozone detection methods.

How to meet Ozone Concentration in Air?

Electrochemistry: This is a commonly used physical analysis method. The principle is to use Electroom Ozone Sensor Module to measure the current produced by ozone between the electrodes, thereby calculating the concentration of ozone. This method responds to fast speed, high sensitivity, strong anti -interference, and is suitable for the detection of ozone in the air. However, there are some disadvantages of this method, such as limited sensor life, required regular calibration and replacement, affected by temperature and humidity.

 

Infrared spectrum method: This is a new type of analysis method. The principle is to use ozone to absorb spectrals with characteristic vibrations in infrared areas. By measuring infrared light, the concentration of ozone is determined by the absorption strength after ozone air. This method is highly sensitive, selective, and is not affected by other factors. However, there are some disadvantages of this method, such as complex instruments, requiring professional operations, and unable to monitor continuously.

 

UV light method: This is a physical analysis method. The principle is to use ozone to have a strong absorption characteristics at 254 nanometer wavelengths. By measured by the transmission rate after ultraviolet light, the concentration of ozone is calculated through the transmission rate of ozone air. This method is convenient to operate, responds fast, is not disturbed by other gas, and can be continuously monitored. However, there are some disadvantages of this method, such as higher instruments, calibration and maintenance, affected by temperature and humidity.

How to choose ozone detection methods?

The selection and application of ozone detection methods depends not only on technology and economic factors, but also the environment and social factors. For example, for urban air quality monitoring, we need to choose a method that can measure the concentration of ozone in real time, continuously, and accurately, in order to timely discover and early warning ozone pollution problems to protect the public’s health and safety.

In addition to the above three commonly used ozone detection methods, there are some other methods, such as iodine quantity, ultraviolet optical method, and chemical lighting method. These methods have their own characteristics and scope, but there are some common challenges and development directions. For example, how to improve the sensitivity and accuracy of ozone detection, how to reduce the cost and complexity of ozone detection, and how to increase the stability and reliability of ozone detection.

 

 

The accurate testing of ozone concentration is essential for environmental protection and human health. This article introduces several common ozone concentration detection methods. These methods have their own characteristics. In different scenarios, you can choose the appropriate method for measurement.
