Abstract

Isokinetic Probe And Pressure Reduction Assembly ABSTRACT
A gas sampling apparatus wherein a retractable isokinetic probe is insertable into a gas flow line through aligned guide tubes and a gas sample is isokinetically conveyed to a converging-diverging nozzle where its pressure is reduced by a controlled shock wave.
