  • Principle Introduction
Principle Introduction:
 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.
Applications :
 It is used for detecting whether the driver and other people who drink alcohol, or detecting whether ethanol steamy exist in other places.

Technical parameters :

Tips:For more parameter information, please refer to the latest manual provided by salesman.
