MNS-4NO-250 Electrochemical Nitric Oxide Gas Sensor
The MANORSHI MNS-4NO-250 is a potentiostatic electrochemical sensor designed for nitric oxide (NO) gas detection.
Nitric oxide and oxygen undergo corresponding oxidation-reduction reactions at the working electrode and counter electrode, releasing electric charges and generating a current. The generated current is proportional to the nitric oxide concentration, allowing the NO concentration to be determined by measuring the current. MNS-4NO-250 Nitric oxide gas se…
