ABSTRACT:
A measuring device for determining the concentration of an absorbable component in a gaseous mixture includes a vertically oriented tubular housing, a vertical hollow tube positioned within the housing and having a heat conducting wall and an open mouth at its upper end; a stub connected to the lower end of the vertical tube for passing a stream of liquid absorbent upwardly through the vertical tube so as to form a free surface area above the mouth of the tube, the liquid absorbent overflowing along the outside of the hollow tube; a stub connected to the housing at a point above the upper end of the vertical tube therein for passing a flow of gaseous mixture past the free surface of the absorbent; a first temperature sensor within the vertical tube adjacent the mouth thereof and covered by the liquid absorbent flowing out of the mouth of the tube; and a second temperature sensor located within the housing to measure the temperature of the gaseous mixture immediately before it contacts the liquid absorbent at the upper end of the tube.
