A portable breath test simulator including a case having a jar support arm extending to one side of the top of the case. A jar containing a known water-alcohol solution is mounted on the bottom of the arm. The case and jar support the simulator. A magnetic power drive located in the case to one side of the jar rotates a magnetic stirrer in the jar. Breath blown into the jar forms an effluent having a known concentration of alcohol and is flowed to a breath test analyzer to be tested.
