The SemeaTech Stack Emission Monitoring Electrochemical Sensors (CO, SO2, NO2 and NO) are designed for stack emission monitoring. They can be used in the environment with those high concentration gases for a long time.
The Stack Emission Monitoring sensor electrodes are much bigger and deposited with thicker chemical compounds. The electrolyte used in these Gas Sensors can sustain tougher environmental conditions than traditional electrochemical sensors. They can continuously detect those high concentration gases.
