MNS-4NH3-100 Electrochemical Ammonia NH3 Gas Sensor
Product Description
MNS-4NH3-100 Electrochemical Ammonia Gas Sensor
The MANORSHI MNS-4NH3-100 is a potentiostatic electrochemical sensor designed for ammonia (NH3) gas detection.
Ammonia undergoes oxidation-reduction reactions inside the sensor, releasing electric charges and generating a current. The generated current is proportional to the ammonia concentration, allowing the NH3 concentration to be determined by measuring the sensor output current. MNS-4NH3-100 Ammonia gas sensor
