Infrared gas analyzer

Abstract

Abstract PURPOSE:To enable a fast response by running a measuring gas between a cylindrical outer box with a separate gas inlet and outlet having an infrared ray transmission window on both sides thereof and a cylindrical filter with a heater coaxial with the inner surface thereof. CONSTITUTION:In an outer box 34 having infrared ray transmission windows 30 and 31 on both sides thereof, a cylindrical gas filter 33 coaxial with the inner surface thereof is mounted removably to make up a measuring cell section. A diffusion space 32 is provided between the box 34 and the filter 33 while the filter 33 is made heatable up to a specified temperature with a heater 37 and the box 34 is provided with a measuring gas introduction port 15 and discharge port 16 facing each other. Thus, the measuring gas can be run along the circumference of the filter 33 and heated thereby enabling effective removal of dust while preventing dew formation of water.
