PRODUCT INFORMATION
TGS 2442 - for the detection of Carbon Monoxide
Features:
* Low power consumption * High sensitivity/selectivity to carbon monoxide (CO) * Miniature size * Low sensitivity to alcohol vapor * Long life and low cost * Low humidity dependency
Applications:
* CO detectors * Air quality controllers * Indoor parking lot ventilation
TGS 2442 utilizes a multilayer sensor structure. A glass layer for thermal insulation is printed between a ruthenium oxide (RuO2) heater and an alumina substrate. A pair of Au electrodes for the heater are formed on a thermal insulator. The gas sensing layer, which is formed of tin dioxide (SnO2), is printed on an electrical insulation layer which covers the heater.
