Abstract: A drinking simulator provides for testing of dental samples under three different condition sets simultaneously. A first tank provides chilled liquid to testing chambers at a first temperature range, a second tank provides heated liquid to testing chambers at a second temperature range and a third tank provides heated liquid to testing chambers at a third temperature range. Shower heads in each of the tanks are provided to shower dental samples with the provided liquid. A human machine interface allows for user control of multiple showering modes and liquid temperatures and additionally displays testing conditions to the user.
