<p>A device for analyzing gases within a moving gaseous stream. The device includes analyzer means (1, 2) located within the stream (41) which is capable of analyzing for the gases contained therein. Substantially surrounding the analyzer means is the combination of a substantially porous body (4) and heater means (5). The combination allows the penetration of the gases to be analyzed but prevents fluctuations in the movement of the gaseous stream which substantially affect and render inaccurate the analyzer while maintaining the analyzer at a substantially constant temperature independent of temperature fluctuations wihtin the gasous stream.</p> |
