The influence of organic vapors (isopropanol. ethanol. and acetone) with different concentrations in air on a response gas sensor based on nanostructured tin dioxide films synthesized by the sol-gel method was studied. It was found experimentally that inject of the gas mixtures containing organic vapors into measure chamber results to an increase of the conductivity of nanostructured ... https://www.poolsproductscanadas.shop/product-category/pool-ladders/
