Electrochemical Nitric Oxide Sensor EC-4NO-250

Electrochemical Nitric Oxide Sensor EC-4NO-250

EC-4NO-250 is a NO sensor which detects Nitric Oxide in level from 0-250 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 NO with good accuracy.
It can be retrofitted easily to existing product designs.
