I believe everyone is familiar with carbon dioxide. It is one of the main components in the air. However, the increase in carbon dioxide will not only cause global warming. But also have a great impact on our daily lives.We will need carbon dioxide detector for monitoring.

For example, in sheds and greenhouses. Too high or too low carbon dioxide will affect the growth of plants or crops. In offices and homes, excessively high concentrations of carbon dioxide can also affect human health. When the concentration of carbon dioxide reaches more than 1%, it will make people dizzy; when it reaches 4 to 5%, people will feel nausea, vomiting, and breathlessness. If it exceeds 10%, people will die.

Therefore, the carbon dioxide detector measures the indoor air quality if there is an abnormality. When the limit value is exceeded, an alarm is triggered or the ventilation system is activated. To ensure that the concentration of carbon dioxide in the air is within a safe range.

Working principle of carbon dioxide detector:

The absorption principle of infrared light source is used to detect carbon dioxide gas in the on-site environment.

Usually the gas to be measured is sucked into a measurement chamber. And one end of the measurement chamber is equipped with a light source. And the other end is equipped with a filter and a detector. The function of the filter is to allow only a certain wavelength of light to pass through. And the detector measures Through the luminous flux of the measuring chamber. The luminous flux received by the detector depends on the concentration of the gas to be measured in the environment.

The carbon dioxide detector adopts a dual-beam, dual-wavelength infrared detector. Which makes the instrument more accurate in the detection process, improves the resolution of the instrument, and has strong stability. The instrument has detection functions such as temperature. The instrument is equipped with a standard gas interface, which can be very convenient for instrument calibration.

In summary, it is an introduction to the working principle of the carbon dioxide detector. Now the requirements for carbon dioxide content in production operations have become more stringent. Carbon dioxide detectors have become an indispensable device in various industries. It is widely used in fields such as breeding, agricultural greenhouses, pharmaceuticals, municipal administration, and sewage treatment. It has become an indispensable protective equipment in industrial safety production.

The carbon dioxide detector can accurately detect carbon dioxide. This is a very useful measurement method because it can help detect problems in the carbon dioxide emission process.

The carbon dioxide detector is an indispensable monitoring equipment for monitoring carbon dioxide around us, and it uses an ABS shell, which is comfortable in the hand, accurate in detection data, and long in service life. We can often see it in scenes such as indoor air detection, gas leaks, and pharmaceutical factories.
