Yes.
For the purpose of the record, I'm holding up a device. This happens to be the Alco-Sensor FST. This is the device that the manufacturers suggest.... The passive detection area is on the top. There are three different types of passive detection with this device that they outline in their technical manual. They are the manufacturers who have suggested that when you're testing an individual, there should be a cup involved on top that you place in here, instead of a mouthpiece, that will attempt to capture more of the breath.
