Product Description
Product Overview
The SGX EC4-2000-SO2 is an industrial Sulfur Dioxide sensor designed for portable gas detectors. It offers a measurement range of 0 to 2000 ppm SO2 with a maximum overload capacity of 4000 ppm. The sensor provides a sensitivity of 12 to 28 nA/ppm SO2 and a linear response across its range. It is designed for long-term use with an expected operating life of 2 years in air and a warranty of 1 year. The sensor operates within a temperature range of -20C to +50C and a humidity range of 15-90% RH (non-condensing).
