Production Description:
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.
Feature:

  • 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.
