Abstract:
A mouthpiece holder and alcohol measuring device combination, the combination comprising:a mouthpiece;a breath alcohol-measuring device;a holder receiving portion which receives the mouthpiece and has a sampling channel leading to the breath alcohol-measuring device;a temperature sensor arranged in a connection area adjacent to the holder and adjacent to the mouthpiece, said temperature sensor being arranged in said sampling channelwith a wall section of said mouthpiece covering an inner wall of said sampling channel at least partially in an area of said temperature sensor;temperature correction means associated with said breath alcohol-measuring device for providing a corrected temperature measurement signal from said temperature sensor based on a sensing of the temperature in said sampling channel before the mouthpiece is connected and a sensing of the temperature in said sampling channel after the mouthpiece is connected to provide an indication ofbreath temperature measurement distortion caused by said mouthpiece; andanother temperature sensor, said mouthpiece having a coupling part in said connection area and said holder including a mount at said connection area with said connection area in said mount defining a mouthpiece holder interface, said another temperature sensor being arranged at said mouthpiece holder interface positioned to detect a surface temperature of said coupling part.
