Sulfur dioxide gas sensor electrochemical SO2 sensor sulfur dioxide detector

Sulphur dioxide is one of the main substances polluting the air and SO2 is recognised as an important corrosive gas in the atmosphere, accelerating the corrosion process of most metals, detection of sulphur dioxide in the air is a regular part of the air inspection process. Sulphur dioxide sensors have shown great superiority in this respect.

For air quality monitoring, we have launched the intelligent "four gases and two dusts" (SO2, NO2, CO, O3, PM2.5, PM10) sensor, which is our new intelligent sensor specifically for gas detection. The gas in the detected area of the instrument flows freely into the gas sensor.

The sensor mainly solves the problems of various types of gas detection, incompatible sensors, complicated calibration, and restrictions on the replacement of core devices; it is easy to operate, accurate and reliable.

Product features 

●Adopting foreign original imported four-electrode gas sensor, with stable performance and high resolution.

●Monitoring NO2, CO, SO2, O3 gases, optional PM2.5, PM10 dust parameters.

● Modular product design, convenient for later maintenance.

This product is suitable for use in enterprise park monitoring, municipal environmental monitoring, mobile environmental monitoring, traffic pollution environmental monitoring, residential area or park environmental monitoring, livestock breeding and other fields.

The four gas and two dust sensors innovatively combine the six pollutant parameters PM2.5, PM10, CO, SO2, NO2 and O3 through a highly integrated structure to achieve 24-hour continuous online monitoring of each pollutant parameter data by gas and transmit the monitored data to people at one time.

PM2.5, PM10 Technical Parameters：

Dust monitoring uses the laser scattering method to measure particle concentrations. When the particles pass through the light sensitive area formed by the focused laser, the light scattered by the particles is collected by a micro photoelectric detector on the detection window. The detector converts the received light intensity signal into a voltage signal, the density of the signal corresponds to the unit concentration value of the particles, the dust concentration value is converted into a coefficient and output in real time through the data interface.

Gas sensor technical parameters：

The gas sensor adopts the principle of electrochemistry to monitor atmospheric concentration, using foreign original imported four-electrode gas sensor, the four-electrode sensor has an extra auxiliary electrode for compensating the zero current, so that it has better response time and anti-interference characteristics.

Carbon dioxide sensors are mainly used to detect the concentration of carbon dioxide in the air.

Carbon dioxide is a colorless and odorless gas, and it is one of the important components of the atmosphere.

As the main reactant of photosynthesis, the concentration of carbon dioxide is directly related to the photosynthetic efficiency of crops, which determines the growth and development, maturity, resistance, quality and yield of crops. However, its excessive content will not only produce a variety of effects such as greenhouse effect, but also endanger human health. When the concentration reaches 0.3%, people will experience significant headaches, and at 4%-5%, they will feel dizzy. Indoor environment, especially in air-conditioned rooms, the environment is relatively sealed, if long periods of time without ventilation, the concentration of carbon dioxide will gradually increase, which is detrimental to human health, according to the indoor air quality standards implemented in 2003, the standard value of the daily average volume fraction of carbon dioxide content does not exceed 0.1%.
