Handheld carbon dioxide meter

1. Overview of handheld carbon dioxide measuring instrument
A handheld carbon dioxide meter is an instrument used to measure the concentration of carbon dioxide in the air. It is portable and can be easily measured in different locations.

(1) Working principle
Some handheld carbon dioxide meters are analytical instruments based on dual-beam dual-wavelength non-spectroscopic infrared (NDIR) sensors, which provide accurate and rapid quantitative determination of carbon dioxide concentrations in public places, indoors and outdoors.

(2) Basic structure
It is usually composed of non-spectral infrared NDIR sensor, sampling pump and microprocessor, and some also have external high-precision digital temperature and humidity sensor.

2. Application field
Environmental monitoring
It can be used in continuous pollutant monitoring system (CEMS), which helps to detect air pollution and greenhouse effect, can carry out continuous real-time environmental monitoring and analysis, and can be used to detect carbon dioxide concentration in public places, indoor and outdoor.

Industrial field
It is widely used in petrochemical, electric power, environmental protection, water treatment, food, occupational safety and health and other fields. For example, in the food industry, it can be used to measure the carbon dioxide gas capacity and air content of carbonated beverages, and in the field of research and development and testing of gas appliances, the relevant detection equipment can detect the carbon dioxide concentration in the exhaust gas.

Other fields
Health and epidemic prevention systems can also play a role, such as air quality detection in some places.

Effects of natural gas leakage on the human body

图片
The effects of natural gas leakage on the human body depend on factors such as the amount of leakage, exposure time, and personal physical condition. The specific effects are as follows: Acute health effects Hazard of suffocation The main component of natural gas is methane. If the concentration in the air is too high, it will reduce the oxygen concentration and cause suffocation. When people are in such an environment, the body will experience symptoms such as difficulty breathing and dizziness due to lack of oxygen. In severe cases, it may lead to coma or even death. Irritation Natural gas may contain toxic gases such as hydrogen sulfide, which irritates the human respiratory tract, causing symptoms such as difficulty breathing and coughing. If you are in an environment containing such gases for a long time, the respiratory tract will be continuously irritated and the damage will be aggravated. Explosion and fire risks After natural gas leaks, once it encounters open flames or high t...

The impact of air quality on health

Impact on the Respiratory System Air pollution is particularly harmful to the respiratory system. Particulate matter (such as PM2.5 and PM10) can enter the respiratory tract, irritating the nose and throat, causing symptoms such as coughing, wheezing, and difficulty breathing. Long-term exposure can increase the incidence of chronic obstructive pulmonary disease (COPD), bronchitis, and asthma. Furthermore, pollutants damage the alveoli and respiratory mucosa, reducing lung ventilation and air exchange, decreasing vital capacity, and gradually weakening lung function, affecting the body's breathing capacity and endurance. Impact on the Cardiovascular System Particulate matter and other particles in air pollution can enter the bloodstream, triggering inflammation and oxidative stress, promoting the formation of atherosclerotic plaques, and increasing the risk of cardiovascular diseases such as coronary heart disease, myocardial infarction, and stroke. Pollutants can also affect the ...

The role of chlorine sensors in agricultural automation

In the field of agricultural automation, although chlorine is not as well known as soil nutrients, temperature and humidity, it will have an impact on agricultural production in certain scenarios. Chlorine sensors can also play an important role. The following explains their roles from different aspects:   Ensure agricultural water safety Monitor irrigation water quality In some areas, water disinfected with chlorine may be used for agricultural irrigation. Chlorine sensors can monitor the chlorine content in irrigation water in real time to ensure that it is within a safe range, avoid damage to crops due to excessive chlorine content, and affect crop growth and yield.   Prevent water pollution If the source of agricultural water is polluted by industrial wastewater, it may contain excessive chlorine. Chlorine sensors can detect this abnormality in time and remind farmers to take corresponding measures, such as changing the water source or further treating the water, to ensur...
