Description
So2 Sulfur Dioxide Sensor
Sulfur dioxide So2 mainly comes from the combustion of sulfur-containing fuels (coal combustion and vehicle exhaust, etc.); for example, the smelting of sulfur-containing ores (especially non-ferrous metal ores containing more sulfur); and the production processes of chemical, oil refining, and sulphuric acid plants where actual sulfur dioxide concentration needs to be detected in order to ensure the safety of the personnel.
ET5-So2 Fixed So2 sulfur dioxide sensor has two models, Portable and Fixed. Here we introduce the Fixed So2 sulfur dioxide sensor.
The concentration of sulfur dioxide gases can be detected regardless of whether the concentration is high or low through 24-hour online detection and real-time display of the data concentration of refrigerant site to play an early warning role in the safety of operations.
