Alcohol Sensor
The FS00703 alcohol sensor is based on high-sensitivity electrochemical principles and has a fast response time without the need to wait. It is pre-calibrated at the factory , eliminating the need for professional equipment for secondary calibration. It can be used in either 0-500ppm (gas alcohol concentration) or 0-500mg/100ml (blood alcohol concentration) output modes, making it more suitable for drinking and driving detection, pre-employment screening, and other occasions, greatly facilitating customer development and use.
