MP-4 Semiconductor Sensor for Flammable Gas

Available:In Stock
R$ 25,90

Application:Air purifiers;Ventilation systems;Air quality monitoring equipment;
Feature:Fast response and resume,Lower consumption,Excellent stability and long life

Production 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.
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:

  • Air purifiers;
  • Ventilation systems;
  • Portable instrument;
  • Air quality monitoring equipment;
  • Air conditioner;
  • and smart home fields;
