Electrochemical Nitrogen Dioxide Sensor EC-4NO2-20

Electrochemical Nitrogen Dioxide Sensor EC-4NO2-20

EC-4NO2-20 is a NO2 sensor which detects Nitrogen Dioxide in level from 0-20 ppm.
It has very excellent repeatability, long term stability, selectivity and resistivity, it is useful in many applications.
As the output current is fairly large, it can detect the low concentration of NO2 with good accuracy.
Nitrogen Dioxide NO2 Electrochemical Sensor EC-4NO2-20 can be retrofitted easily to existing product designs.
