Description

CDW-16A SO2 Sulfur Dioxide Sensor

SO2 sulfur dioxide online sensor is a device specifically designed to detect sulfur dioxide content in the environment. The sulfur dioxide gas sensor has many important features. The first is high sensitivity, which can detect very low concentrations of sulfur dioxide. This is essential for early detection of environmental pollution problems and for monitoring subtle changes in air quality.

Secondly, it has good accuracy and stability, can work reliably under different environmental conditions, provide accurate data for environmental monitoring and industrial production, and its working principle is usually based on specific chemical or physical reactions.

Dimnsion & Mounting

Application

Environmental monitoring:

◉SO₂ is one of the main pollutants in the atmosphere, causing environmental problems such as acid rain and chemical smog. In cities, industrial areas and environmental monitoring stations near traffic arteries, sulfur dioxide gas sensor are widely used to monitor atmospheric sulfur dioxide concentrations in real time. Through continuous data collection over a long period of time, the time-space variation of SO₂ concentration can be mapped to help the environmental protection department understand the air quality situation in a region.

◉In some special places, such as buildings near boiler rooms with sulfur-containing fuels, chemical laboratories, etc., indoor air may contain a high concentration of SO₂. SO₂ sulfur dioxide online sensor can be used to monitor indoor air quality and ensure the health of indoor personnel.

Energy field:

◉Engineers or technicians handling processes like converting traditional fossil fuels to clean energy, for instance, in coal gasification combined cycle power generation (IGCC) systems, can use a sulfur dioxide sensor. They can use it to monitor the generation and removal of sulfur dioxide during this process. This monitoring provides them with a basis for optimizing energy conversion efficiency and reducing pollutant emissions.
