Alcohol concentration sensor FS00700C is a type of semiconductor ethanol probe that utilizes precise automated production and testing equipment to reduce interference from human factors, ensuring good accuracy and consistency of data even in mass production. This methanol probe is particularly suitable for portable product applications due to its small size and ease of integration into various designs.
The gas-sensitive material used in the gas sensor is a semiconductor material with low conductivity in clean air, with a built-in heating wire and metal electrode. When alcohol vapor exists in the sensor’s environment, the sensor’s conductivity will increase. And the change in conductivity increases with the concentration of alcohol gas. So ethanol gas sensor can sense the alcohol concentration in the air through the change in conductivity.
1. Small and easy to integrate design
2. Data is precise and has good consistency
3. Low power consumption and long service life
4. High sensitivity to low-concentration pollutant gases
