In so2 monitoring, there are factors to consider when choosing or planning an appropriate monitoring method in the workplace. The need for so2 monitoring should first be considered. In fact, that need should be truly felt in the workplace. Sources and levels of contamination should also be taken into account, as well as the need for real-time responses in case high levels of SO2 are detected in the area. Areas for monitoring should also be considered in determining the right method for so2 monitoring.

Exposure to SO2 poses as a great health hazard not only for the workers but also for the people living near these workplaces. Exposure to this gas eventually leads to respiratory problems. If a person is exposed to sulfur dioxide even for quite a short period of time, he or she may suffer from asthma. In the long run, that person may suffer from severe cardiorespiratory ailments. When persons are exposed to sulfate particulate, which is a by-product of an interaction between SO2 and other gases and particulate matter. Sulfate particulate can be carried through the air from one place to another, and it tends to stay in the atmosphere for longer periods of time. SO2 and sulfate particulate are frequently associated with premature death. 

With all these things in mind, the need for so2 monitoring is highly recognized. In fact, many companies and even governmental organizations showed interest in using an SO2 analyzer. This analyzer can help a lot in checking the amount of particulates in the atmosphere before planning and implementing a gas monitoring strategy for that particular workplace. The gas analyzer also aids the company to keep SO2 emissions within regulation limits ordered by the government.
