Electro Optical Components, Inc. Stack Emission Monitoring Electrochemical Sensor, 3 Series 3SO2-2000

The 3 Series (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 sensor electrodes are much bigger and deposited with thicker chemical compounds. The electrolyte used in the 3 Series Gas Sensors can sustain tougher environmental conditions than the 4 and 7 Series sensors. The 3 Series can continuously detect those high concentration gases. The 4 and 7 Series are designed to work in the relative clean environment most of time but detect toxic gases if there are leakages.
