Model: VAP 5
The vacuum gauge VAP 5 relies on the fact that the thermal conductivity of the residual gas in the vacuum
chamber is a measure for the gas pressure. The thermal conductivity of gases is proportional to the
pressure within a certain range and is related to the molecular mass.
The thermal conductivity of gases and vapours varies with their molecular mass. The gauge has been
adjusted for air (nitrogen) at the factory.
