MP-3B Alcohol Gas Sensor Lower Consumption Small Size Fast Response And Resume Highest Sensitivity For Detecting Whether Ethanol Steamy Exist In Other Places
MP-3B Alcohol Gas Sensor Lower Consumption Small Size Fast Response And Resume Highest Sensitivity For Detecting Whether Ethanol Steamy Exist In Other Places
MP-3B model with advanced planar construction is comprised of heater and metal oxide semiconductor material of subminiature Al2O3 ceramic plate, fetch out electrode down-lead, encapsulation in metal base and cap. When the target gas (alcohol) exists , The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.
Features:
* Lower consumption
* Small size
* Fast response and resume
* Highest sensitivity
* Excellent stability and long life
* Easy circuit and big signal output
* Excellent selectivity
Application :
It is used for detecting whether the driver and other people who drink alcohol, or detecting whether ethanol steamy exist in other places.
