<p>PURPOSE:To obtain a gas analyzer which can measure the H2O content of a sample gas with a high-speed response. CONSTITUTION:This gas analyzer is constituted so that infrared rays emitted from an infrared light source 1 and reflected by a reflector 2 can be condensed through a condenser lens 3 and made incident to a cell 4 for samples and a PbSe detecting element 15 is provided in a detector 5 to which the infrared rays are made incident after passing through the cell 4. In addition, an optical filter 16 which can pass rays of light of a wavelength band which is 2.6mum in center wavelength and 4% in half-width is provided on the opposite side to the element 15.</p> |
