When unpacking the quality free processing of the appliance falls on, it is small, handy and looks to the simple design very classy, like a cell phone. Is supplied in a shock-proof hard plastic box that contains extra mouthpieces and a solid fabric bag in addition to the manual. The alcohol tester is ready for operation immediately, the handling and operation simple, it must be operated only one button to turn on and off, the instructions are easy to understand for the user and quickly understandable. I've tried this breathalyzer together with a fellow policeman who has years of experience with this type of equipment. New to the unit is already integrated mouthpiece for pulling out. The slider on top of the device must be operated with astonishingly little effort, and the replacement of the mouthpiece does not work quite as easy as I had imagined. Another new feature is the replaceable sensor unit, which is used to calibrate the instrument. Thus, not the entire unit must, as before, to be returned. We have been drinking alcohol, and as recommended by the manufacturer, waited about 15 minutes until the first test, not only the residual alcohol is measured in the oral mucosa, but the actual alcohol concentration in the body. Turn on, take a deep breath and then blow in in the previously mouthpiece long as evenly until a clicking sound is heard. The sensor determines after blowing very fast and reliable, whether we should leave the car better. This sensor, which reacts chemically to alcohol in the breath, the values determined with very minor departures, all within the tolerance range of +/- .03 to .05 per thousand documents, compared to the professional police equipment. The per thousand - value is immediately thereafter displayed digitally, almost as fast as the professional police unit! Also in the repetition did not disappoint this tester, it provided fast, reliable results. I was surprised, look how different the same amounts of alcohol in different people, but it depends indeed on individual factors such as food intake before the test or by the body weight of the subjects from.
One hundred percent results delivered according to a statement of the police anyway just a blood test in the laboratory. These measurements are used to first check the blood alcohol level. The breathalyzer is not cheap, but it can be with a professional device quite be compared and is in many situations virtually certain. When in doubt, it is of course always better to leave the car.
