  • Breath test simulator with headspace fan and method
    Patent number: 9810682
    Abstract: A breath test simulator includes a jar holding an ethyl alcohol/water solution. A heated metal top housing on the top of the jar supports a baffle plate extending over the solution. Ethyl alcohol/water vapor is flowed from the solution into a headspace between the baffle plate and the top housing. A rotary fan in the headspace circulates vapor in the headspace and moves the vapor against the housing to heat the vapor. The heated vapor is circulated and heats the jar to speed warm up of the simulator and assure the headspace vapor is maintained at a desired temperature prior to discharge to a breath test instrument to be calibrated.
