Electrochemical Alcohol Sensor ME2-C2H5OH-13×13

  • ME2-C2H5OH-13×13-1.png


ME2-C2H5OH-13×13 is a fuel cell type alcohol chemical sensor. Alcohol and oxygen have a corresponding redox reaction on the working electrode and the counter electrode and release charges to form a current. The magnitude of the generated current is proportional to the alcohol concentration and follows Faraday's law. The level of alcohol concentration can be determined by testing the magnitude of the current.


Maximum measurement limit: 2.0 mg/L
Sensitivity: (115±85)uA/(mg/L)
Repeatability: ±0.006mg/L

Vehicle Alcohol Test

The picture shows a common "ignition interlock system" with an alcohol detection function in the United States. This lock is connected to the ignition system of the car. Before ignition, the driver must blow air to ensure that the alcohol concentration in the body does not exceed the standard. and the car can start.


Alcohol Detector

Strengthen the punishment of drinking and driving in all the country to reduce the vicious traffic accidents caused by drunk driving. This involves testing a person's alcohol level and using equipment to do the testing. An alcohol detector is an effective tool for measuring the alcohol content in the human body.
