Abstract
Abstract A method of testing a fluid is disclosed which comprises passing a main flow of a fluid through a conduit; inserting into said conduit a probe having an inlet opening which faces downstream of the conduit, or is disposed in a chamber communicating with the conduit, the inlet opening communicating with an outlet opening which is disposed in an end surface of the probe; the said main flow, in passing through the conduit, causing a sampling flow of the fluid to be drawn from the conduit, and to be passed through the probe from the inlet opening to the outlet opening, and so back to the conduit; and testing said sampling flow.
