The S120 Oil Vapor Monitor is designed to monitor oil contents and dew
point (option) in compressed air and gases within the permissible
operating parameters. These parameters can be found in the technical
data section.
The S120 is mainly used in compressed air systems in industrial
environment. The S120 is not developed to be used in e plosive areas.
To evaluate its applicability in e plosive areas, please contact the
manufacturer.
