ABSTRACT:
An apparatus for use in determining the presence and/or concentration of one or more selected materials in a given stream or aggregation in a conduit or vessel, the apparatus comprising (a) a support member constructed from a thermally conductive material and having a first, internal end for inserting into the stream or aggregation when the apparatus is placed in service and a second end positioned externally of the conduit or vessel in use, wherein the support member defines a groove therein of which at least a portion extends into the stream or aggregation in use, (b) a conduit positioned and supported substantially wholly within at least that portion of the groove in the support member which extends into the stream or aggregation in use, and (c) a temperature monitoring device positioned within the support member, whereby the temperature of the conduit/stream or aggregation interface may be measured by thermal conduction from the supporting groove portion of the support member to the temperature monitoring device contained within the support member.
