PCT No. PCT/GB95/01452 Sec. 371 Date Aug. 25, 1997 Sec. 102(e) Date Aug. 25, 1997 PCT Filed Jun. 20, 1995 PCT Pub. No. WO95/35495 PCT Pub. Date Dec. 28, 1995A resistive gas sensor having a WO3 sensing element is especially useful for detection of low concentrations (1 ppm or less) of ozone in air. The WO3 element is a porous layer with a 30-60% porosity and less than 50 micrometer thick, having in general a sufficiently open porous microstructure and high surface area to give satisfactory response to ozone. The sensor is used for detection of low ozone concentrations at a working temperature in the range from ambient to 600 DEG C. |
