The probe (6) has a magnesia-packed heating filament within a stainless steel tube to which a thermocouple is bonded with wiring (80,81) to a signal-processing circuit (8). It is energised from a current generator (7) to produce the necessary heat flux into a reaction chamber. - Two chambers (1,2) are linked by a tube (3) and equipped with heat exchangers (4,5) in circuits contg. electrically-operated valves (11,10). A thermal pulse or step is produced by the generator (7), and the response curve of the thermocouple is integrated, or the temp. attained after a given interval detected.
