The ChemWatch S is designed for monitoring corrosivity in a protected environment to identify such as leaks, breakthrough gases, and other sources of disruption that can lead to corrosion of electronic components. The device can also be used in exceptional cases to determine corrosivity in uncontrolled rooms. Corrosivity is usually caused by acid gasses such as H2S, SO2, SO3, Cl2, Cl2O, NOx, or NH3
