YJJ Electrochemical Hydrogen Sulfide Sensor H2S NE4-H2S-100 with Long-term stability 2% signal value/month
Product Description:
Electrochemical Hydrogen Sulfide Sensor (H2S) NE4-H2S-100
Features:
NE-H2S is a hydrogen sulfide gas sensor for industrial applications. In addition to the standard models (H2S-100, H2S-200 and H2S-500), three other models described on the next page are also available. Users can choose the most suitable model according to their application. The output current is very large, which means that it can detect relatively low concentrations of hydrogen sulfide, and the sensor has good selectivity, resistance and repeatability, so it can be used in a wide range of fields.
