MP-4 Flat Surfaced Flammable Gas Sensor

Household CH4 Gas Sensor

Applications :

*It is widely used in domestic gas leakage alarm, industrial flammable gas alarm and portable gas detector.

Product Advantages:
  • *Lower consumption
  • *Small size
  • *Fast response and resume
  • *Highest sensitivity
  • *Excellent stability and long lifey
  • *Easy circuit and big signal output
  • *Excellent selectivity
Product Description:

MP-4 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 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.
