Electrochemical Nitric Oxide Sensor EC-4NO-250
EC-4NO-250 is a NO sensor which detects Nitric Oxide in level from 0-250 ppm.
EC-4NO-250 Nitric Oxide Sensor 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.
Nitric Oxide (NO) Electrochemical Sensor EC-4NO-250 can be retrofitted easily to existing product designs.
