Principle Introduction
| MEWOI-MIX8030 Alcohol Sensor is an electrochemical sensor developed by Mixsen. Alcohol and oxygen on the working electrode and counter electrode are subjected to oxidation-reduction reaction correspondingly. This produces the electric current. The current is directly proportional to the concentration of alcohol and following the Faraday’s law. Through measure the current to get the concentration of alcohol. |
Features
small volume High sensitivity Linear output long life |
Application
Residential and commercial , Alcohol testing for traffic safety , Alcohol testing before works , Coin-operated alcohol detector
