ABSTRACT:
A conjoint probe apparatus having an adjustable extendable probe end for embedding in the porous media for in situ sensing of changes in the dielectric constant of the carbonaceous constituents undergoing microwave pyrolysis, and a mechanism for indicating the sensed changes, for adjusting the radiation in dependence upon such changes, the degree of extension of the probe end being adjustable in dependence upon the sensed frequency of the attendant radiation.
