Abstract

A reaction calorimeter probe (1) arranged for calorimetric in-situ measurements in a pumpable reaction medium, comprising an inner tube (2) arranged to have the pumpable reaction medium flowing through the inner tube, an outer tube (3) extending coaxially of the inner tube at a radial distance from the inner tube, a sealed space (6) between the inner tube and the outer tube, wherein the space is provided with a vacuum, a first temperature sensor (7) arranged at an inlet end (8) of the inner tube, a second temperature sensor (9) arranged at an outlet end (10) of the inner tube, at a distance from the first temperature sensor, wherein the first and second temperature sensors are arranged in the space and in contact with the outer surface of the inner tube for measuring an absolute temperature of the inner tube, wherein the first and second temperature sensors are arranged to enable determinations of absolute temperatures with a resolution which is better than 1 μΚ, and a calculation device connected with the first and second temperature sensors, which calculation device is arranged to determine a first absolute temperature by means of the first temperature sensor, a second absolute temperature by means of the second temperature sensor, and to determine a temperature difference between the first and second absolute temperatures.
