Abstract
A portable fluid analyzer has a sampling section with flow passage structure for sealing engagement with a discharge port of a zwickel fitting or the like and retainer structure for engagement with the fitting. The retainer structure is urged by a spring towards a retaining position and is movable, by a manual operator towards a released position. When the retainer structure is engaged with the fitting and the manual operator is released, the sealing member is urged by the spring into engagement with the fitting's discharge port. The analyzer also includes an analysis chamber connected to the discharge end of the flow passage structure and monitoring means for providing an output as a function of a constituent of the fluid in the analysis chamber.
