Product Details Product specification download
Principle Introduction:
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.
Applications :
It is widely used in domestic gas leakage alarm, industrial flammable gas alarm and portable gas detector.
Technical parameters :

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