The high-pressure steam apparatus makes it possible to measure
steam pressure in a temperature range of 100-250 °C. This allows
for investigations to be performed on real gases and vapours.
Typical equilibrium states between gas and liquid phases can be set
up. For this purpose, water is heated in a closed pressure chamber
at constant volume. The heat of vaporisation is determined at
various temperatures from the measurement of vapour pressure as a
function of temperature.
- No open flame in the setup - Reduction of thermal hazard
- No gas burner required - Easy to operate and no consumption of consumables
