Historical information

The Orsat was returned to the Historical Collection by Len Taylor, former staff member of SMB. For a period of time it was with Gary Price who rebuilt the Orsat to working order. Gary used a similar apparatus at Sidchrome and Ballarat Heat Treatment Pty.
The Orsat apparatus is used to measure volumes of Carbon Dioxide, Oxygen, and Carbon Monoxide within a fixed volume of a sample of gas.
