MP-7 Carbon Monoxide GAS SENSOR

MP-7 adopts advanced planar construction production technics, using MOS material formed by micro AL2O3 ceramic tube and

heater, electro-down-lead be fetched out, and are fixed into a metal base and cover. Adopting low and high temperature circling

the conductance, change it to be output signal which relatively to the gas concentration.

Character

* High Sensitivity to CO

* Mini Size

* Fast response and resume character

* Excellent Stability and long life

Application

* They are used in gas leakage detecting equipment in family, industry and commercial field, fire resistance/

safety detection system.

* CO gas leakage alarm and detector
