The Marcet Boiler

Illustrates the pressure and temperature relationship for saturated steam

The TD1006 Marcet Boiler is a simple experiment to show the relationship between pressure and temperature for saturated (wet) steam for comparison with published results.

Key features

  • Compact, bench-top unit
  • Based on the classic Marcet boiler experiment
  • Stainless steel vessel (boiler) for long life and ease of maintenance
  • Proves the Antoine equation for saturated steam
  • Vessel (boiler) has viewing window to see the boiling process and the water level
  • Simple and safe to use – includes temperature cut-out switches and a pressure relief valve
  • Electronic sensors measure boiler temperature and pressure – shown on a digital display in both SI and traditional units (including absolute values)
  • Can connect to TecQuipment’s Versatile Data Acquisition System (VDAS®)

Additional Information


You can do tests with or without a computer connected. However, for quicker tests with easier recording of results, TecQuipment can supply the optional Versatile Data Acquisition System (VDAS®). This gives accurate real-time data capture, monitoring and display, calculation and charting of all the important readings on a computer (computer not included).


Learning Outcomes

  • Variation of saturated steam pressure with temperature
  • Confirmation of the Antoine Equation
