A sulfur dioxide detector monitors the concentration of this toxic gas in air and alerts you when it reaches unsafe levels. This personal protection device is indispensable in hazardous chemical applications such as the synthesis of chemicals (including sulfuric acid), disinfection, and metal refining. It is also used in the paper and food industries as a bleaching agent. Sulfur dioxide (CAS 7446-09-5), commonly known as SO2, is a common pollutant generated by burning coal and oil in industrial processes, automobile combustion, and volcanoes.

sulfur dioxide detector is corrosive, irritating to the nose and eyes, and in high concentrations can make breathing difficult – especially for people with asthma. It can also be a deadly hazard in confined spaces where it can build up in the lower areas and form a poisonous cloud.

Unlike most portable gas detectors which show you how much time is left on the battery, our SO2 gas detector displays actual live readings at all times and has a backlit display to improve readability. It is easily maintained by simply removing the sensor element and replacing the batteries.

Identifying Sulfur Dioxide: The Role of Sulfur Dioxide Detectors in Air Quality Monitoring

It is important to perform frequent gas detector calibrations – often daily if you are using it in LIFE-THREATENING and DANGEROUS applications. Performing a bump test (exposing the detector to a known gas) helps prevent drifting in the sensor readings and ensures that your instrument is working properly. For this, you will need a special gas calibration kit that includes the required bottle of target gas and tubing.
