NE4-NO2

NE4-NO2

NE4-NO2 is a nitrogen dioxide gas sensor.  Since the output current is fairly large, it can detect the low concentration of NO2 with good accuracy.  Additionally, as it has very excellent repeatability, long term stability, selectivity and resistivity, it is useful in many applications.

By adhering to industry standards for size and connection orientation, the NE4-NO2 can be retrofitted easily to existing product designs.
