Overmax AD-04 equipped with a professional electrochemical alcohol sensor works similarly to police breathalyzers, at the same time maintaining modern and compact design. During first 24 months after the purchase you can calibrate your breathalyzer for free. Not only does the LCD display show you the measurement results, but it also turns red each time the concentration of alcohol in your breath exceeds the accepted limit. What is more, the breathalyzer has now an additional feature – its memory can store up to 20 recent test results.
AD-04 is a handy device, extremely useful for any driver. It comes out with an included car charger (a convenient USB cable), 10 interchangeable mouthpieces and a functional case.
