The utility model relates to an on-spot quick blood alcohol concentration tester. One of two electrodes of an alcohol concentration sensor is connected with a sampling resistor, the other end of the sampling resistor is connected with one end of a numerically controlled precision regulated power supply, and the other electrode of the alcohol concentration sensor is connected with the other end of the numerically controlled precision regulated power supply; both ends of the sampling resistor are connected with a digital-to-analog conversion module, and the digital-to-analog conversion module is connected with a computer system. The invention has the following advantages that: the on-spot quick blood alcohol concentration tester can instantly test the blood alcohol concentration of a driver on the driving spot, and thereby can instantly judge whether the driver drinks or not on the spot. Consequently, the utility model can effectively stop drunk drivers, thus avoiding the occurrence of traffic accidents.
