The SGX-4OX is an electrochemical oxygen sensor designed for industrial gas detection applications, particularly portable gas detectors. It operates using a chemical reaction that produces a current directly proportional to the concentration of oxygen present. The sensor features a standard 4-series circular housing with an industry-standard footprint. It provides a reliable output signal for concentrations up to 25% oxygen with an expected operating life of over two years in air. This specific variant contains lead and is intended for use where RoHS exemption applies or in regions not subject to the directive.
