YJJ 4NO2-20 CLE-0321-400 Nitrogen Dioxide Electrochemical Sensor
Product Description:
4NO2-20 CLE-0321-400 Nitrogen Dioxide Electrochemical Sensor
Features:
Performance Characteristics
electrochemical gas sensor is a microfuel cell original, but it is developed on the basis of the original oxygen sensor. It has been successfully developed because of low power consumption, good selectivity, high sensitivity and low efficiency. The main design features of the electrochemical gas sensor are capillary adsorption of liquid electrolyte, small holes limit gas diffusion, so that all target gases can reach the electrode surface and react with it
