This is a set of two TOPLAND ETIQUETTE CHECKER breath checkers, designed to detect both bad breath and alcohol. ◼️ Main Features: The main feature is that it combines the bad breath check function and the alcohol check function, which were previously separate, into one device. It has two operating modes: bad breath mode and alcohol mode. When you breathe into it, it displays the level of bad breath or alcohol in 6 stages. The device is equipped with a gas sensor that detects the components contained in your breath. In alcohol mode, in addition to the 6-stage display, it can also display an estimated amount of alcohol in your breath, up to 0.5mg, in 0.05mg increments. It uses two AAA alkaline batteries for power, and the battery life is approximately 120 uses. The lifespan of the sensor is unknown. Body size: 110 x 30 x 18mm (width x depth x height) Weight: 52g including batteries (Batteries are not included) Individual sales are also available, so please consider them as well. #TOPLAND_BadBreathChecker There are some minor scratches on the LCD screen, but overall, it is in relatively good condition. It has been cleaned and disinfected with alcohol. Immediate purchase is welcome. It will be shipped in simple packaging using recycled materials.
