PURPOSE: A drunkometer is provided to prevent freezing at a low temperature, to ensure a stable and accurate operation, and to reduce unnecessary voltage consumption. CONSTITUTION: A drunkometer comprises: housing(20), an inhalation tube(10), an alcohol measuring unit(30), an anti-freezing unit, and a power supply unit. The inhalation tube is attached to the outside of the housing for outbreathing. The alcohol measuring unit generates a current by a chemical reaction and measures the concentration of alcohol by the generated current. The anti-freezing unit is coupled to the alcohol measuring unit and prevents freezing of the alcohol measuring unit. The power supply unit supplies driving power to the anti-freezing unit and the alcohol measuring unit.
