ン濃度測定器用オゾン分解フイルタ。 This product is related to ozone decomposition filters used in ozone concentration measuring instruments using the ultraviolet absorption method.A metal mesh made of copper, titanium, etc. is used as a catalyst carrier, and the catalyst carrier is dipped in a manganese salt solution such as manganese nitrate and dried repeatedly to form a surface of the metal mesh. A manganese nitrate layer is formed on the metal net, and this metal net is heated in the air to a temperature of 300 to 500°C to form and adhere a manganese oxide layer on the surface of the metal net carrier. A gas filter that is made by placing a fibrous or porous material between each of the layers to serve as a separator, and housing the whole in a sealed container, and gases other than ozone that have absorption in the ultraviolet absorption wavelength band of ozone gas Ozone concentration measurement using ultraviolet absorption method that selectively decomposes only ozone gas without decomposition or adsorption, so that the measured value is not affected by gases other than ozone and accurately measures the concentration of ozone alone. A handy ozone decomposition filter.
