Abstract
Further studies are reported on a novel room temperature tin oxide-pla tinum sensor for carbon monoxide (CO). The expected porous nature has been confirmed by scanning electron microscope pictures of these senso rs. Pore sizes were 0.1-10 mu m. Recovery studies confirm that high re sistance sensors recover more quickly. During the recovery a second fi re can be detected and there are no signs of self-poisoning by CO. Pre liminary results are presented for temperature and humidity cycling. ( C) 1998 Chapman & Hall.
