Mini Gas Sensors
4 Series
Introduction:
Mini sensors are suitable for most applications where size is limited. Only 20 mm in diameter, it is ideal for portable or limited size packaging for automotive, commercial and residential applications.
Available in toxic, oxygen, and dual Hydrogen Sulfide/Carbon Monoxide (COSH).

Toxic Gas Sensors:
The toxic sensor works by reacting to the concentration diffused through a permeable membrane and reacting to chemicals to produce a linear output proportional to the con-centration. In addition, the toxic sensor incorporates a third reference electrode.
Oxygen Sensors:
The oxygen sensor works by reacting to the concentration of oxygen diffused through a permeable membrane and reacting to chemicals to produce a linear output proportional to the concentration.
